Ohervet/Bjet_MCMC: v1.2.0: Cutomized parameter boundaries, Gaussian seeds for MCMC p0, improved output plots

New features:

• Users can now customize the boundaries for each parameter in the config file
• Multi-normal variables (Gaussian) seeds can now be implemented as a starting point in the MCMC process. The seeds are created from the file bjet_mcmc/p0_file.txt that is retrieved when using the option p0=gaussian in the config file. The location of the p0_file.txt is hardcoded, this will be improved in a further update.

Optimization:

• Added likelihood profile corner plot with set default binning of 30
• Optimized corner plots boundaries
• Use pdf instead of svg for outputs
• Removed outdated parameter custom_alpha2_limits
• Raise an Exception when not enough statistics to probe the 1-sigma parameter space

Bug fixing:

• Fixed a bug that crashed the code when the model matches exactly an upper limit value at the machine precision level
• Raise Exception when not enough statistics to probe the 1-sigma parameter space
• Bug fixed on min_max_params_1sigma function (ndim was hardcoded), no clear evidence that it really affected the outputs
• U_BLR output was given without considering the frequency shift of the blob motion. This only affects the number in the output log file. The EIC-BLR process is done correctly.
