No easy way to change number of tests

[kanwren]

Currently, there's not an easy way to change the number of tests run from the default (100). Even if you do reach in and change it manually, it doesn't change the successful test output, which as far as I know is hardcoded to "✓ passed 100 tests."

It would be nice to change the number of tests for tests where a potential failure case might be particularly rare.

i'm not sure what the best way of doing this would be.

i may need to implement some monad transformer on top of PropertyT IO that adds ReaderT PropertyConfig. Then variants of each of the lawsCheck functions that take in a PropertyConfig could be added. this would require a bunch of internal work, but would minimise external impact.

this will actually be easier if you are using tasty-hedgehog. related to #13
