This version has some tweaks to the cosmo chains/file reading code to make it more streamlined to use.
- `load_params` now parses the .paramnames file into a dict of plaintext-LaTeX pairs instead of a tuple of lists of each param name format
- `load_chains` now understands glob patterns, removing the need to call it repeatedly in a for loop to load multiple chain files into one dataframe. Also has a new option `params_only` which is on by default that skips the first two columns of the chains (the sample weight and the likelihood).
