feat(push): add an option to specify targets

[caila-marashaj]

Overview

These changes to push allow us to specify targets in the form of presets, and only those targets will be built and copied onto the robot. To allow this, a new update_shortsha function grabs the existing manifest file from the robot, and updates the sha of the specified targets.

You can specify just one or multiple targets, for example:
./push 10.10.10.10 --targets pipettes-single pipettes-multi gantry-x.
./push 10.10.10.10 --targets pipettes-single

If this argument isn't used, the script will run the same as it did before, meaning it will build and update all firmware presets.

Logically, it behaves independently of the sensors argument, meaning you can use the firmware-g4-sensors build preset, and either send the full build or just the hex files for whichever nodes.

Changelog

• add targets parameter
• add a function to grab and update the robot's manifest file with new sha
• only build and send desired firmware if given targets

Test Plan

For all nodes:

• Make sure sha only changes for specified targets using can_control
• Check that the manifest file is updated as expected
• Make sure sensors argument still works with and without targets
• Make sure everything works the same if targets isn't used

Review Requests

• Is there any particular order where I should call update_shortsha different from where I am?
• Are there any ways this might break anything that I should test?

Looks good but I do want to make sure that you can still use this without these args and get the old behavior

The rear panel produces .bin files, you'll need to include those as well.

can this be combined into this?
f"{target}(.*).hex"
the regex should be valid

[vegano1]

We should define a list of targets and validate them against the user input, something like this.

TARGETS = [
    "head",
    "gantry-x",
    "gantry-y",
    "gripper",
    "pipettes-single",
    "pipettes-multi",
    "pipettes-96",
    "hepa-uv",
    "rear-panel",
]

for target in args.targets:
    if target not in TARGETS:
        print(f"Unknown target {target}", file=sys.stderr)
        continue

    # do work here

We actually do something similar in the scripts/subsystem_versions.py script

[vegano1]

Same as the above comment, the scripts/subsystem_versions.py script validates the filenames, it could be useful to check that.

Changes look good to me, I left a few comments.
We should validate the --target args against a known list of targets.
Other than that the change works, I tested it locally!

nice work!
