Progress bar for find_MAP()

[PrzeChoj]

The user will run the M-H algorithm for a long time on his machine. The process has to be more informative and eye-pleasing than right now.

The progress bar was added to Metropolis-Hastings.

However, I would love it to give out some information:

• Estimate the time left
• If the algorithm finds the new best permutation, print a different character

The progress bar for the best_growth algorithm with max_iter=Inf is not supported, and I currently do not know how to design it. Any idea would be appreciated.

When one calls find_MAP(return_probabilities = TRUE), calculating the probabilities is timely. I decided to add the second progress bar that starts to go after the first one ends to separate those processes. I'm unsure if I communicated it clearly in the documentation and if this could be done more intuitively.

There is a progress package in R, but:

1. I think it does not support printing different characters when a new best is found
2. works poorly for multithreading

Packard CLI looks promissing…
