Reliance on `sqlalchemy.types.DOUBLE` is not reflected in dependency version option space

[kklein]

This commit, released with version v0.4.2 introduces a reliance on sqlalchemy.types.DOUBLE.

Yet, the sqlalchemy docs indicate that said object has only been introduced with sqlalchemy version 2.0: https://docs.sqlalchemy.org/en/20/core/type_basics.html#sqlalchemy.types.Double

This can also be seen in code: sqlalchemy 1.4.54 (highest release <2.0) doesn't include DOUBLE in its types module:
https://github.com/sqlalchemy/sqlalchemy/blob/rel_1_4_54/lib/sqlalchemy/types.py

Yet, this necessity of sqlalchemy being >= 2.0 is not reflected

• in the readme, which states

  SQLAlchemy version between 0.7.3 - 2.0.x.

• in the feedstock's recipe, which doesn't have any lower bound on sqlalchemy
• in the setup.py, file which only requires 'sqlalchemy>=0.7.3'

Hi @kklein ,
Thank you for reporting this issue.
I will add a condition for the SQLAlchemy version in the code with a new PR.

Thanks again!
