Picrust2-v2.6.3 (#399)

Some updates:
- Added a check for empty trait tables: this was specifically an issue if users created custom trait tables and these were empty/summed to zero for one of the domains
- PFAM names were updated: in the PICRUSt2-SC database these used the names given by Eggnog as annotations. These have now been mapped to PFAM ID's (where possible) so that they match the description map files. The add_descriptions script can now be used with the PFAM ID's again. Note that there were a few PFAM names from the Eggnog annotations that didn't have PFAM ID's; these have been left as they are but they have no additional descriptions. 
- Script naming for the scripts that work with only a single domain, rather than the PICRUSt2-SC separate reference files for bacteria and archaea, has been updated. This reflects that these scripts aren't only for use with the oldIMG database, but can be for fungi, either/or of the bacteria/archaea files, another custom database, etc.

Update setup.py

Update README.md

Fix picrust2-env.yaml dependencies (#378)

1. ete3 has to be installed from etetoolkit channel. conda-forge does not work, even though it is listed on https://anaconda.org/conda-forge/ete3.
2. Installing sepp 4.5.5 requires python3.10.
3. Runnning test requires typeguard 4.4.2 to be specified separately.

Update picrust2-env.yaml dependency versions

Hoping this will fix issues with Mac installs.
dendropy 4.5.2 -> 5.0.1
gappa >=0.8.0,<=0.8.5 -> >=0.8.0
hmmer >=3.1b2,<=3.2.1 -> >=3.1b2
sepp 4.4.0 -> 4.5.5
