ansi_up 2.1.0

ansi_up: ^2.1.0 copied to clipboard

Fixed a regexp getting recompiled every time an AnsiUp is instantiated and decodeAnsiColorEscapeCodes is called for the first time.

The regexp is now compiled once during the lifetime of the program.

Removed AnsiUp.ansiColors and AnsiUp.palette256 members.

These members were not useful to users, and they didn't need to be instance members. ansiColors is not a constant, and palette256 is now initialized only once (instead of every time an AnsiUp is initialized).
