Separate out package code from paper code

[avik-pal]

Currently, the package has a lot of fluff which is not really needed. I will branch it out to paper which contains the scripts and everything needed to reproduce the results from the paper.

Stuff that need to be removed:

• experiments directory -- Maybe convert that into usage examples.
• scripts directory -- Has some scripts for distributed training using MPI (will move them to FluxMPI which seems to be an appropriate place for their usage)
• Inside src
  • solve.jl -- See Upstream DiffEq Patches #33
  • logger.jl -- Time to place it somewhere appropriate. Have been copy-pasting that file in all my projects 😓
  • datasets.jl -- Again not relevant to DEQs

Stuff to be added:

• Some documentation would be good (even I forget how to use a few of those functions 😅 )
