* Add signed to unsigned conversion to SafeCast * Update SafeCast exception message * Add test for SafeCast int to uint conversion - Update SafeCastMock - Add tests for SafeCast int256 to uint256 * Update SafeCast int to uint definition Apply suggestions from code review. Co-Authored-By: Nicolás Venturo <nicolas.venturo@gmail.com> * Update test for SafeCast int to uint conversion * Update SafeCast test after code review - Change "downcasts" to "casts" - Move test closer to its function * Fix error in SafeCast toUint256 description * Fix breaking error in SafeCast * Add uint256 to int256 conversion to SafeCast - Add function - Add mock - Add test * Update SafeCast unsigned to signed conversion - Update error in conversion to be more clear - Update constants in test to be powers of 2 instead of shifts * Add changelog entry * Update SafeCast tests - Add minus in INT256_MIN for clarity Co-Authored-By: Nicolás Venturo <nicolas.venturo@gmail.com> Co-authored-by: Nicolás Venturo <nicolas.venturo@gmail.com>
