support colons in SGR character attributes
Patch by Mikhail Kot <to@myrrc.dev>
With some modifications to behave more like xterm (see note below).
Example:
printf '\033[48;2;255:0:0mtest\n'
https://invisible-island.net/xterm/ctlseqs/ctlseqs.html
Some notes:
"CSI Pm m Character Attributes (SGR).
[...]
o xterm allows either colons (standard) or semicolons
(legacy) to separate the subparameters (but after the
first colon, colons must be used).
