Detect archictecture in `assert_loads_correctly`

[RunDevelopment]

Since some architectures can have highly varying state dicts depending on their hyperparameters, I added an optional detect: bool = True argument to assert_loads_correctly. If enabled, assert_loads_correctly will check that the detect method of the architecture correctly identifies a model of its architecture. This means that our detect methods aren't just tested by example model files, but also by the diverse set of models used to test parameter detection.

Nice, it already found some bugs.

Error messages now look like this:

AssertionError: Failed to detect lambda: RGT(resi_connection="3conv"),
15/16 keys accepted.
1 missing key(s):
  - conv_after_body.weight

Changes to fix the 5 errors:

• HAT: I figured out that pixelshuffle is the only valid upsampler, which simplified some code.
• DAT: The checked keys made assumptions about parameters, which weren't always true.
• RGT: The checked keys didn't account for the resi_connection parameter.
• FeMaSR: The test model used technically correct but nonsensical parameters.
• AdaCode: The test model used technically correct but nonsensical parameters.
