"termcolor" version is too restrictive

[John-Nagle]

"Simplelog" insists on termcolor "1.1". This lock-in to an old version causes version clashes with "wgpu", which wants a more modern "^1.4.1". Please fix versioning.

How about just "1"?

That was already fixed in #131, but there hasn't been a release (#141).

ping @Drakulix , can we get a release? This is also causing build failures for me. (I suppose this comment overlaps with #141)

Should be fixed for 0.12.2, same future proofing will be applied to master at some point before an eventual 0.13 release.
