Implement method to compare with other libraries

[rgommers]

Set up a list (preferably auto-updating) which gives information about which other (Python) libraries contain a certain function. E.g.:

• concatenate supported by: dask, jax, cupy
• median supported by: ... (not dask)

[kgryte]

While not auto-updating in the sense of a cron job which automatically runs against various library APIs, you can find a library comparison here: https://github.com/kgryte/numerical-library-apis/blob/3df4f7f39910458320f50576becd613f55e95ecd/data/joins/unified_join.csv
