Release v4.1.1

This release fixes a few issues when increasing the competition count.

• Downloaded model limit is now adjusted dynamically by competition count.
• Competition specific weights rather than subnet weights are used when prioritizing models to keep. (This helps clear out UIDs who swap the competition they are competing in from their previous competition).
• Threshold for model prioritization from other top validators is lowered to 5% weight as weights are spread more thinly over multiple competitions.
