bump minimal PyMySQL version to 1.0.0 (#713)

while we do not yet strictly require it this simplifies maintenance.
e.g. the xfailing test from #712 gets a different error type starting with PyMySQL 0.10.0.
it will also allow us to adopt the backwards incompatible changes from PyMySQL 0.10 and 1.0.
as our test suite only runs with the latest supported PyMySQL version we currently cannot
reliably test older versions either.
