Config options

[Dreamsorcerer]

Problem

Users need to be able to pass configuration options for blueprints. This adds basic support for CLI arguments, envvars and config files.

Closes #1082.

Solution

Typer is not compatible with this kind of dynamic configuration, therefore we basically tell it to give us arbitrary strings via -o and then do all the processing ourselves, along with providing our own help output.

How to Test

Should be able to add --help to dimos run to see blueprint options and then configure them with -o, env vars and JSON config files. For example:
RERUNBRIDGEMODULE__MEMORY_LIMIT="50%" dimos --simulation run unitree-go2 -o voxelgridmapper.voxel_size=1 --config=foo.json
