Update quickcheck to 1.0

[est31]

Quickcheck had a 1.0 release. We should update the dev-dependency to it. There have been attempts in #368 but there were memory allocation errors in CI:

test conversions::sample_rate::test::divide_sample_rate ... ok
memory allocation of 107029510102 bytes failed
error: test failed, to rerun pass '--lib'

Caused by:
  process didn't exit successfully: `D:\a\rodio\rodio\target\debug\deps\rodio-0e4135a1fbf0228b.exe` (exit code: 0xc0000409, STATUS_STACK_BUFFER_OVERRUN)
Error: Process completed with exit code 1.
