neurokit2 + PyWavelets

[Litsardos]

I would like to request adding neurokit2 and PyWavelets to the pypi.flet.dev package index.
These packages are needed for signal processing and analysis.

pywavelets 1.9.0 is now available on pypi.flet.dev for both iOS and Android.

neurokit2 doesn't need a package on our index — it's pure Python, so it installs straight from PyPI. All of its other native dependencies (numpy, scipy, pandas, scikit-learn, matplotlib) are already available. Just add both to your pyproject.toml dependencies as usual:

dependencies = [
  "flet",
  "neurokit2",
]

One tip: import neurokit2 pulls in matplotlib.pyplot, which needs a non-GUI backend and a writable config dir (for its font cache) on mobile. Point it at Flet's app storage before the first import:

import os

mpl_dir = os.path.join(os.getenv("FLET_APP_STORAGE_DATA", ""), "matplotlib")
os.makedirs(mpl_dir, exist_ok=True)
os.environ.setdefault("MPLCONFIGDIR", mpl_dir)
os.environ.setdefault("MPLBACKEND", "Agg")

import neurokit2 as nk

Using FLET_APP_STORAGE_DATA (persistent) rather than FLET_APP_STORAGE_TEMP means the font cache is built once instead of on every cold start.

Let know if u face any issues.
