-doswizzle option does not work in Linux CLI since version 4.5.52

[Tatsi]

When compressing a texture to BC7 with compressonator CLI Linux version 4.5.52 the -doswizzle option no longer does anything. In Linux CLI version 4.4.19 and in Windows CLI version 4.5.52 it works. Example command to reproduce the issue:

compressonatorcli -mipsize 1 -doswizzle -fd BC7 input.png output.dds

It's expected that the R and B channels would be swapped, but they aren't.
