SRHD with CR

[ChunYen-Chen]

This PR includes the works Can the symmetric Fermi and eROSITA bubbles be produced by tilted jets? from @zengbs.

Updates

1. SRHD supports CRs and gravity.
2. New Fermi bubble test problem.

TODO

• Upload the initial condition. (yt.upload is malfunctioning now)

Results

Fermi bubble test

@ChunYen-Chen I see in your presentation these lines:

Code:
1. Add more unphysical checks. e.g. passive scalars
2. Bugs fix of EoS: The initial guess of HTilde when solving temperature.
3. The unit of temperature output is changed from code unit to Kelvin.

Regarding 2: we fixed such a bug in the merged SRHD PR. Was there another one?
Regarding 3: I thought that the output temperature units were already in Kelvin? We had this discussion previously as well, and yt certainly seems to think the units are Kelvin.

@jzuhone You are right that both 2 and 3 have already been merged into GAMER early this year in #185. IIUC, @ChunYen-Chen's slides are referring to @zengbs's own branch used in his Fermi/eROSITA bubbles paper that didn't incorporate #185.

@ChunYen-Chen @zengbs Please correct me if I'm wrong.

@hyschive The branch is updated to the latest main branch.
