Allow any lal dictionary option and add numerical_relativity_file

Hi @gregory.ashton @colm.talbot,

Since bilby_pipe!371 (closed) was in conflict with parallel_bilby, I have changed the strategy and modified bilby instead so now it works.

With this MR, bilby_pipe!371 (closed), !893 (closed) and !845 (closed) can be deleted/closed.

I have performed an NR injection (SXS0143) with parallel_bilby and compared with old results we had. Below there are some example plots. The values in the labels indicate the precessing version and final spin prescription I am passing to PhenomXPHM through the LAL dictionary. Blue and green are runs with the same PhenomXPHM settings but comparing an old private bilby and this MR. They both agree, and in red you have different PhenomXPHM settings and that's why it is a bit different.

This run was performed with the current master version of bilby_pipe and pBilby. Here they are the git hashes from the parallel_bilby_generation log:

'bilby_version': '1.0.3: (CLEAN) ef4a2f37 2020-11-18 10:00:09 +0100',

'bilby_pipe_version': '1.0.2: (CLEAN) c5febc3 2020-11-18 09:24:49 +0100',

'parallel_bilby_version': '0.1.6: (CLEAN) e59e706 2020-11-12 14:32:24 +1100'

The config file for pBilby I used was config.ini
