hyprland/submap: allow pango markup.

[coreydoughty]

It would be nice to allow simple pango markup in "format": "{}", of the "hyprland/submap" module from the hyprland.conf file.

Example hyprland.conf:

...
$submapName = Note:  <b>S</b> <i>some app</i> <b>O</b> <i>other app</i>
bind = $mainMod, A, submap, $submapName
submap = $submapName
bind = , s, exec, someapp
bind = , o, exec, otherapp
bind = , escape, submap, reset
submap = reset
...

I was able to get this to work by editing the code in src/modules/hyprland/submap.cpp and changing lines 71-72 from

auto submapName = ev.substr(ev.find_last_of('>') + 1);
submapName = waybar::util::sanitize_string(submapName);

to

auto submapName = ev.substr(ev.find_first_of('>') + 2 );

Without these edits or something similar the original code cuts/removes everything from before the last > plus one character. This works without the pango markup due to the submap string starting with submap >> . With the pango markup it jumps to the last > in the string.

Also the sanitize_string function converts the > and < to entities. There may be a better way to escape the string than using the sanitize_string function. Removing the line worked for me for now.

Tested on 0.12.0
