GitOrigin-RevId: ac60fd3cf4a24023184376687da28373d14b781a

This mirrors the robotpy files for the following projects:
- apriltag
- datalog
- hal
- ntcore
- romiVendordep
- wpilibc
- wpimath
- xrpVendordep

This excludes cscore and the halsim wrappers for at this time.

NOTE: This does not hook these projects up to the build system, just simply mirrors the files. The building will take place in a follow up PR to make it easier to review the changes necessary to build.

AprilTag

Adding new field to AprilTagFields

Adding field JSON

  1. Add a field layout CSV file to src/main/native/resources/edu/wpi/first/apriltag
    1. See docstring in convert_apriltag_layouts.py for more
  2. Run convert_apriltag_layouts.py in the same directory as this readme to generate the JSON
  3. That script overwrites all generated JSONs, so undo undesired changes if necessary
  4. Update the field dimensions at the bottom of the JSON
    1. Length should be in meters from alliance wall to alliance wall
    2. Width should be in meters from inside guardrail plastic to plastic

Java updates

    1. Add enum value for new field to AprilTagFields
    2. Update AprilTagFields.kDefaultField if necessary

C++ updates

  1. Update src/main/native/include/frc/apriltag/AprilTagFields.h
    1. Add enum value for new field to AprilTagFields
    2. Update AprilTagFields::kDefaultField if necessary
  2. Update src/main/native/cpp/AprilTagFields.cpp
    1. Add resource getter prototype like std::string_view GetResource_2024_crescendo_json()
    2. Add case for new field to switch in LoadAprilTagLayoutField()
