Create PyPI pip package

[emiliom]

And conda package?

Update [@leewujung 2023/12/08]:

• We've decided to create a pypi package
• Probably also a good idea to create a conda package

[leewujung]

From Sept 29 notes we decided to create a PyPI package.

I propose that we change the package name to echobiome so that it is more descriptive of what the package is for.

[leewujung]

The name change is now tracked in #144. I'll remove the "?" in the issue title since we've decided to do this.

This was included as part of PR #241 and can now be closed.
