Monitor.* without ~here:[%here] or ~info

In this library all the use of `Monitor.protect`, `Monitor.try_with` have no location information. So it makes debugging a little tedious when you have an exception catched after the return of the function.

Expected behavior: At least know the name of the function called. But indeed without proper backtrace I will not know the call point in my code, so this lack of information is perhaps not the real issue.

Start by locating the library uses of Monitor.protect and Monitor.try_with, then compare them with the location-aware ~here:[%here] or ~info forms mentioned in the issue. Done means exceptions caught after a function returns provide at least the called function's name or other useful location information.
