Set a specific font style for a font family (e.g.: `Bold`, `SemiBold`, etc.)

Is your feature request related to a problem? Please describe.
I want to use JetBrains Mono Nerd Font SemiBold on macOS, but I can only use JetBrains Mono Nerd Font

Describe the solution you'd like
Maybe a --font.style flag, that we could use to set --font.style SemiBold

Describe alternatives you've considered
On linux I can actually use JetBrainsMono NF SemiBold, but somehow that doesnt work on macOS. Even tho I installed the same font files.

Additional context

tree -d 2 | freeze -l ANSI --font.family "JetBrainsMono Nerd Font"

tree -d 2 | freeze -l ANSI --font.family "JetBrainsMono Nerd Font SemiBold"

This issue might be in the SVG renderer from chroma:

Doesn't seem like the font weight and style are configurable.

Nevermind, chroma seems to support this:

Could this be integrated into freeze?

I propose: --font.style and --font.weight
