feat: PickHybProbeOnly() task in prymer

[emmcauley]

Closes #11.

Context

We want to be able to design internal probes as part of prymer. This PR adds PickHybProbeOnly as a Primer3Task.

Overall, this PR is based off main and highlights mostly code moving and renaming. This PR also adds some simple dataclasses:

1. Adds ProbeParameters() for probe design parameters
2. Adds ProbeWeights() for penalties associated with probe params
3. Updates existing tests

More tests are required and I intend to add them in a follow-up commit. Additionally, for Primer3 to serve thermodynamic scores for primer design tasks, the thermodynamic parameters and weights need to be added to ProbeParameters() and ProbeWeights() (this will be in a future commit).
