* Implement MagicSharp2013 Add the MagicKernelSharp (2013) resizing kernel. The implementation is based on "Solving the mystery of Magic Kernel Sharp" by John P. Costella (https://johncostella.com/magic/mks.pdf) * Move new enums to the end to preserve backwards compat * Add 2021 filter and rename * Simplify some expressions * Remove the incorrectly named Plus variant * Mark resize_filter param unused * Implement MagicKernelSharp2013 * Separate the implementataion of 2013 and 2021 kernels
