QuerySpace creation fix

[osopardo1]

Description

In this PR, we fixed a bug in which the creation of the range filter that creates a QuerySpace wasn't taking into account the possibility of column transformations in Spark.

For example, imagine that we index the parameter named column1. If we filter by:

regex("prefix", "column1", 1) == "a"

Instead of filtering by the regex expression, QuerySpaceBuilder would understand that we are trying to filter all the values that contain column1 == "a"

Checklist:

Here is the list of things you should do before submitting this pull request:

• New feature / bug fix has been committed following the Contribution guide.
• Add comments to the code (make it easier for the community!).
• Change the documentation.
• Add tests.
• Your branch is updated to the main branch (dependent changes have been merged).

How Has This Been Tested? (Optional)

Please describe the tests that you ran to verify your changes.

Change test that (unfortunately) passed because the filter range belonged to the same file (prefix_versace and versace have very similar values of hash and had been stored together).
Now the test checks if we return the whole dataset in that type of scenarios.

Later on, we can investigate how to manipulate more complex predicates. But let's start with the basics.

Test Configuration:

• Spark Version: 3.2.x
• Hadoop Version: 3.4.x
• Cluster or local? Local
