- update to 0.7.0:

* Now all prints are done via the logging module.
* ``drms.const`` was renamed to `drms.JsocInfoConstants`

``requester``.
* Removed ``debug`` keyword argument from `drms.HttpJsonClient`
* Now all prints are done via the logging module.
* Removed all FTP options.
* All keywords have to be passed by reference, no more
positional keywords arguments are allowed.
* Added "ruff" to the pre-commit and fixed the errors.

* Modified `drms.client.Client._convert_numeric_keywords` to use
a row-centric approach for handling hexadecimal strings.
* Modified `drms.utils.to_datetime` to work with Pandas 2.0.
- Do not build for Python 3.6, due to no NumPy.
