support only_best option

[visr]

Edit: see post below about the only_best option that is new in PROJ 9.2.

PROJ 9.2.1 is already picked up by this package through PROJ_jll v900.200.100.

• update tests
• re-run wrapper wrap PROJ 9.2.1 #90

The two remaining test failures can be fixed by enabling network access for those transformations. Otherwise we get these separate errors:

hgridshift: could not find required grid(s)
vgridshift: could not find required grid(s)

using Proj
Proj.enable_network!(false)
trans2 = Proj.Transformation("EPSG:32632", "EPSG:2027", always_xy = true) # fails, passed before, passes with network

I suspect this is related to the new ONLY_BEST option. This option looks like a great addition, but as I understand the PR it shouldn't break anything since it defaults to off. So I don't understand why it would affect our tests. This need some more investigation.

Also perhaps we should add some support for the option just like pyproj:

pyproj4/pyproj#1236

I don't mind this breaking change, it should be the default imho.
