Problem
---------
The compute_is_used function currently parses through a huge amount of
data using the _read_group ORM function. Which causes some performance
issues in large databases.
Objective
---------
Improve performance of the said function.
Solution
---------
Instead of reading the data on whole tables (ex.account_move_line), we
read the relation table between the modules and the taxes. This is done
using SQL queries with the EXISTS statement.
Furthermore, the code logic is modified so that if all the taxes for
which we compute `is_used` have been found, we don't look further in
other modules since doing this cannot add an new relevant information
and actually slows down the computation.
