Cache files downloaded by download_weekly_pointing_file #69
Description
Describe the performance issue
sunkit_instruments.fermi.download_weekly_pointing_file doesn't cache the files it downloads, instead downloading a fresh copy each time it's called. e.g. calling it twice with the same date downloads identical files to different folders:
(sunpy) 🐊 dstansby@Davids-MBP sunkit-instruments % python test.py
/var/folders/m4/v0b71w0s22z34l90psw9j82w0000gn/T/tmp41ub2_7t/lat_spacecraft_weekly_w604_p310_v001.fits
(sunpy) 🐊 dstansby@Davids-MBP sunkit-instruments % python test.py
/var/folders/m4/v0b71w0s22z34l90psw9j82w0000gn/T/tmpklqmgxz9/lat_spacecraft_weekly_w604_p310_v001.fits
It would be good if these files were cached to prevent extra downloads.
To Reproduce
import sunpy
sunpy.map.Map(...)
etc

Better yet, we should just be using the data manager (https://docs.sunpy.org/en/stable/how_to/remote_data_manager.html) and deprecate this function entirely.
