mflike-plik branch: import is broken #78
Description
Hi,
We are reimplementing the way Cobaya deals with external likelihoods, to gain some new features, such as automatic installation with a simple mention in the input file. I was starting by adding the external likelihoods which are already in
https://cobaya.readthedocs.io/en/latest/likelihood_external.html#list-of-external-packages
Among them, there is a reference to a class implemented in the mplike-plik branch. The installation in that case works, but it throws an error at importing, breaking the workflow of the installer:
Traceback (most recent call last):
File "<string>", line 1, in <module>

raise ValueError('No template for model '+filename+' found in ' + str(data_path) + ' ls: ' + str(os.listdir(data_path)))
^^^^^^^^^^^^^^^^^^^^^
FileNotFoundError: [Errno 2] No such file or directory: './plikmflike/fgspectra/data/'
I reckon it has to do with data files not being included, as specified in the README, but the error should be thrown at instantiation, not at import, don't you think?
In any case, does it make sense to add this likelihood (the one in the mflike-plik branch) to the new list, or will it be superseded soon by a new version?
