fix: inspectdb not match data type 'DOUBLE' and 'CHAR' for MySQL

* increase:
1. Inspectdb adds DECIMAL, DOUBLE, CHAR, TIME data type matching;
2. Add exception handling, avoid the need to manually create the entire table because a certain data type is not supported.

* fix: aerich inspectdb raise KeyError for double in MySQL

* feat: support command `python -m aerich`

* docs: update changelog

* tests: verify mysql inspectdb for float field

* fix mysql uuid field inspect to be charfield

* refactor: use `db_index=True` instead of `index=True` for inspectdb

* docs: update changelog
