Supporting geoalchemy2

[neatek]

The issue arises when using a column with the type Geometry("POINT") from geoalchemy2, as attempting to utilize FastCRUD results in an error: 'utf-8' codec can't decode byte 0xe6 in position 5: invalid continuation byte. It would be beneficial to add support for geoalchemy2. If that's not feasible, is there an alternative approach for handling such a column type? Or is it necessary to write custom queries and routes? As always thank for you answer!
