What is claimed is: 1. A dryer appliance, comprising: a cabinet; a drum rotatably mounted at the cabinet, the drum defining a drying chamber configured for receipt of articles for drying, the drum comprising a rear wall, the rear wall of the drum being fixed to the cabinet; and a sheet dispenser comprising a housing mounted to the rear wall of the drum, the housing defining a storage volume and an outlet, the storage volume configured for receipt of a plurality of dryer sheets for dispensing, the outlet positioned contiguous with the drying chamber, a roller mounted to the housing within the storage volume, and a motor coupled to the roller such that the motor is operable to rotate the roller, the roller configured to urge the plurality of dryer sheets in the storage volume towards the drying chamber through the outlet of the housing when the motor rotates the roller. 2. The dryer appliance of claim 1 , wherein the storage volume of the housing is configured for receiving the plurality of dryer sheets as a vertical stack. 3. The dryer appliance of claim 1 , wherein an outer surface of the roller comprises a plurality of projections distributed over the outer surface of the roller. 4. The dryer appliance of claim 1 , wherein a mass of the roller is no less than two-tenths of a kilogram. 5. The dryer appliance of claim 4 , wherein the mass of the roller is no less than one kilogram. 6. The dryer appliance of claim 1 , wherein the sheet dispenser further comprises a spring coupled to the roller, the spring configured to urge the roller against a topmost one of the plurality of dryer sheets in the storage volume. 7. The dryer appliance of claim 1 , further comprising a controller, wherein the motor is a stepper motor, the controller in operative communication with the stepper motor, the controller configured to operate the stepper motor a number of steps based at least in part on a determined number of sheets for dispensing. 8. A sheet dispenser for a dryer appliance, the dryer appliance comprising a drum, the drum defining a drying chamber configured for receipt of articles for drying, the drum comprising a rear wall, the sheet dispenser comprising: a housing mounted to the rear wall of the drum, the housing defining a storage volume and an outlet, the storage volume configured for receipt of a plurality of dryer sheets for dispensing, the outlet positioned contiguous with the drying chamber; a roller mounted to the housing within the storage volume; and a motor coupled to the roller such that the motor is operable to rotate the roller, the roller configured to urge the plurality of dryer sheets in the storage volume through the outlet of the housing when the motor rotates the roller. 9. The sheet dispenser of claim 8 , wherein the storage volume of the housing is configured for receiving the plurality of dryer sheets as a vertical stack. 10. The sheet dispenser of claim 8 , wherein an outer surface of the roller comprises a plurality of projections distributed over the outer surface of the roller. 11. The sheet dispenser of claim 8 , wherein a mass of the roller is no less than two-tenths of a kilogram. 12. The sheet dispenser of claim 11 , wherein a mass of the roller is no less than one kilogram. 13. The sheet dispenser of claim 8 , wherein the sheet dispenser further comprises a spring coupled to the roller, the spring configured to urge the roller against a topmost one of the plurality of dryer sheets in the storage volume. 14. The sheet dispenser of claim 8 , further comprising a controller, wherein the motor is a stepper motor, the controller in operative communication with the stepper motor, the controller configured to operate the stepper motor a number of steps based at least in part on a determined number of sheets for dispensing.
