Description:Using Cascadia Code PL makes symbols smaller

Additional info:
* Package version: 2.1.0+36+gd0bf73a1-
* 10-nerd-font-symbols.conf symlinked from /etc/fontconfig/conf.d/
* Cascadia {Code, Mono} PL NOT set as `monospace` font

The original variant of Cascadia Code/Mono do not contain Powerline symbols. Hence, it may be advisable to use the Cascadia {Code, Mono} PL variants. However, using the variants in conjunction with this package with ttf-iosevka-nerd installed results in the symbols being smaller than usual.

The ttf-iosevka-nerd package only contains the fonts and no fontconfig configuration files. However, removing ttf-iosevka-nerd results in the problem being fixed. This strongly suggests that font substitution quirks are responsible for this rendering error.

As detailed below, adding the Cascadia {Code, Mono} aliases to 10-nerd-font-symbols.conf fixes this problem.

Steps to reproduce:
0. Install ttf-nerd-fonts-symbols, ttf-cascadia-code, and ttf-iosevka-nerd
1. Use the Powerline variant of Cascadia (Cascadia {Code,Mono} PL) in your preferred terminal
2. Nerd font symbols become smaller

(Suggested) fixes:
0. Add Cascadia {Code, Mono} PL alias to 10-nerd-font-symbols.conf.
Tested fix in per-user configuration

1. Notify maintainer of ttf-iosevka-nerd of this problem. However effectiveness is doubted as 10-nerd-font-symbols.conf contains aliases for a large number of fonts, which indicates this affects all fonts that do not have an alias.
This task depends upon

`10-nerd-font-symbols.conf` presumably only covers patched fonts provided by Nerd Fonts. You might be better off rolling your own font configuration file, eg. https://gitlab.com/polyzen/dotfiles/-/blob/master/workstation/.config/fontconfig/fonts.conf.

Cascadia Code is patched by Nerd Fonts. However, using Cascadia Code (original variant) yields an undesirable result in that the Powerline symbols do not display properly (independent of having `ttf-iosevka-nerd` installed). Switching to Cascadia Code PL fixes this issue, but the icons tend to be smaller (only with `ttf-iosevka-nerd`). The end result of using this package should be nearly (if not actually) identical to the third screenshot, which is the Nerd Fonts-provided CaskaydiaCove Nerd Font ( https://github.com/ryanoasis/nerd-fonts/tree/master/patched-fonts/CascadiaCode ).

On a high note, I had to contend with having ttf-iosevka-nerd installed because of the `ttf-nerd-font` dependency of one of my packages. With the new update this is not needed, so I can revert back to not having `ttf-iosevka-nerd` installed with this.

I am suggesting this as a workaround, since this should really work out of the box with `Cascadia Code` and with any other package installed. It may help though that the PL variant is officially provided by Microsoft ( https://github.com/microsoft/cascadia-code#font-variants ).

Is this still an issue?
