Phys from_sbpy fails for comets

[jrob93]

High-level problem description
Phys.from_sbdb works fine for asteroids but seem to not like querying comet designations

What did you do?

from sbpy.data import Phys
phys = Phys.from_sbdb("147P")

What did you expect?
I expected the code to return physical data for the comet.

What did really happen?
The code gave an error:

FieldError: Field M1 is not an instance of <class 'astropy.units.quantity.Quantity'>

It seems that astroquery SBDB is not providing units for all the fields that sbpy expects units for. The following code does the query successfully and the OrderedDict does not have units for M1 etc

from astroquery.jplsbdb import SBDB
sbdb = SBDB.query("147P", phys=True)
print(SBDB.schematic(sbdb)) 

Provide information on your environment:
macOS Monterey 12.4
sbpy version: 0.3.1
astropy version: 5.0.1
numpy version: 1.21.2

Thanks, and I can confirm this bug, and have a fix. If you need a workaround in the short term, then get the data from astroquery as you do above, and apply the unit manually.

Ah, except that won't get it into the Phys object without major work. I'm not sure there is an easy workaround.

No worries, the astroquery solution is fine for me right now!
