SkyCoord, not SkyFrame!
renamed method BaseQuery.request to BaseQuery._request
IRSA dust coordinates parsing
minor typo
use transform_to everywhere

add backward-compatibility: convert "frames" to SkyCoords if needed
Vizier .fk5 -> transform_to
fk5 -> transform_to('fk5')
remove .galactic, .icrs
fix a forgotten test
