An easy-to-use, command line optimizer for PNG files

Whats new in version 1.7.83:
• Check sBIT chunk data to see if reduction to gray or to 8-bit is permitted,
• i.e., the RGB sBIT values are equal to each other or the sBIT values are
• not greater than 8, respectively.
• Do not try to make_opaque if the tRNS chunk is found.
• Added warning when ignoring an invalid commandline option.
• Improved brute_force handling with specified level, filter, or strategy.
