Add support for more primitives

[BD103]

This is a draft PR that adds support for more Java primitive types. Closes #148.

Todo

• [x] long
• [x] float

Optional

• [ ] short
• [ ] byte
• [ ] char

[BD103]

@rbrott this is now ready as a minimum viable product. I do have a few additional questions, though:

• Should I add support for short, byte, and / or char?
  • I feel they're less common, so I don't know if it's worth implementing it (yet).
• Do you want me to remove the test configuration or is it fine to keep?
• Should the web client check that the number is less than $2^{63}$? It seems to silently error out when a too large number is given.

@rbrott this is now ready as a minimum viable product.

Great work, thanks for the patch.

* Should I add support for `short`, `byte`, and / or `char`?  
  * I feel they're less common, so I don't know if it's worth implementing it (yet).

I agree, those can wait.

* Do you want me to remove the [test configuration](https://github.com/acmerobotics/ftc-dashboard/pull/150/files#diff-f2ed284d340b830a45aacf109e4d4895ebbc84710b1868472bf3724f6618e382) or is it fine to keep?

Fine to leave it.

* Should the web client check that the number is less than 263? It seems to silently error out when a too large number is given.

I don't think we need to address proper bounds right now. It would be nice to add full support for longs in the future, but this is a useful improvement as-is.

@rbrott would you mind publishing a new release with this pull request? My team needs the feature, but I'm unsure of how to depend on a Git repository.
