Koni Marti ab941ebc6a filters: posix compliant rewrite of calendar filter
Rewrite of the awk calendar filter to make it posix compliant. Tested
with awk --posix (awk -V = GNU Awk 5.1.1). Also added some improvements
to readability and formatting.

This complements commit 3ef4a3ca05 ("filters: try and make awk scripts
posix compliant").

Robin Jarry 3ef4a3ca05 filters: try and make awk scripts posix compliant
\x escape sequences are GNU specific. Use the octal escape code instead.

filters/calendar is beyond help. It would need a complete rewrite to
make it work with POSIX awk.

Robin Jarry d2c239292e filters: fix colorize urls in signatures
When a signature contains a line that starts with an url, the url is not
highlighted properly:


The trailing m of the signature color start \x1b[38;2;175;135;255m is
considered as part of the URL scheme (i.e. mhttps:// instead of
https://). Colorize the URLs first before wrapping with the signature

Robin Jarry df8c129235 filters: port colorize to awk
Python is not available on all systems. Port the colorize filter to awk
as it is a more widespread POSIX utility.

Users are free to copy the filter into their home dir and tweak the
colors to their needs. The highlighted items are:

  Item            Red     Green   Blue      Color

This assumes a terminal emulator with true color support and with

Daniel Xu ea4fe71360 Strip carriage returns (^M) when filtering emails
Presumably some email servers will transform newlines into carriage
return new lines to better support windows users. I can't prove this but
that's the best explanation I have for my hosted email provider

Without this patch, I was seeing annoying `^M`s at the end of every
filtered line.

escapes the plus symbol in the regex on line 28.
