Add enabling of CAMP for chemistry

[jcurtis2]

• Add CampCore() that takes a filename argument
• Add alternative initializations for GasData, AeroData to accept CampCore
• Example notebook of partmc/scenarios/5_camp
• Handle json input files in notebook

[slayoo]

@jcurtis2, in the recent commits, there are:

• a refactor of the time-stepping logic making the code shorter and a bit more Pythoni
• a workaround for the JSON files issue (inability to ship seperate files with notebooks) by downloading them from github.com

Still, the new CAMP notebook fails for a variety of reasons:

• on Windows:

ERROR (PartMC-592148911): Solver failed for aerosol-phase with code -6
terminate called after throwing an instance of 'std::runtime_error'
  what():  845183800

• on macos-14 (Apple Silicon):

libc++abi: terminating due to uncaught exception of type std::runtime_error: to_json not implemented for this type of object: <_PyPartMC.CampCore object at 0x109d731b0>

• on Linux:

free(): double free detected in tcache 2

Could you please check on your machine? Thanks

OK, managed to get a backtrace for the macOS error (libc++abi: terminating due to uncaught exception of type std::runtime_error: to_json not implemented for this type of object: <_PyPartMC.CampCore object at 0x109d731b0>):

OK, one more hint from the logs: this is a minimal 2-line reproducer of the Linux double free or corruption (fasttop) error:

import PyPartMC as ppmc
ppmc.Photolysis(ppmc.CampCore())
