Fix bs4 recursion issue

Why these changes are being introduced:
During processing of one set of deleted Alma records, bs4's internal
process was hitting Python's internal recursion limit. Raising the
recursion limit seems to solve the issue without a notable impact on
performance.

How this addresses that need:
* In the helpers module where this issue occured, sets Python's internal
  recursion limit to 10000 instead of the default 1000.

Side effects of this change:
If we ever hit a real infinite loop, it will take longer for Python to
crash.
