Fix/latex deps

[ravjot07]

Closes #41.
The docs recommended a full TeX Live install (texlive-full, on the order of ~1.5 GB) for PDF/PNG/SVG. The project only needs a small slice of that stack, and the generated document was loading newpxtext / newpxmath unconditionally, which pulls in a heavy font stack on many systems.

What changed
latex_wrapper in core.py — newpx is now optional. The wrapper uses \IfFileExists{newpxtext.sty}{...}{} so Palatino-style fonts load when present and compilation still succeeds with default fonts when they are not.
CI (.github/workflows/test.yml) — Replaced texlive-full with texlive-pictures, texlive-latex-extra, plus ghostscript and pdf2svg so CI mirrors a lean setup and runs faster with less download.

How to verify
pytest tests/ (as in CI)

@ravjot07 Thanks, I just noticed you have sent us a draft proposal today - unfortunately there won't be time for us to give this draft a proper review before the formal GSoC deadline, which is also today: https://developers.google.com/open-source/gsoc/timeline - so you won't benefit from any suggested revisions we might have offered. However please feel free to submit the application via the GSoC website anyway as we'll see it there. Thanks again for your effort and we'll aim to respond properly soon.

Thanks for the response @edwardchalstrey1 will really appreciate if you can suggest some other issues that I can work on
