[WIP]added the latest .whl files for the license_expression(Part of the issue:adding License Expression to DeltaCode)

[pratik0316]

In this PR I changed the thirdparty packages by inserting new .whl packages for license_expression(version:1.2,old version 0.99)

@MaJuRG this PR is meant to update the TPP to have the latest license_expression library.Regarding the integration of this library I have a few queries:
I was testing the functionalities of license_expression
It had the options to :
is_equivalent : for testing two expressions
parse:for parsing a library exp
contains:for checking weather an exp is contained in another
and many more
But in DeltaCode currently we are currently dealing with mainly files(and its status), if any license is present in a file it takes the additional info from it (like owner, category) in a string expression for each deltas.
So for what purpose(s), can we eventually make use of this library?

@Pratikrocks the license_expression library has the ability to simplify() a complex expression down to its base license_key (and category) elements.

Since we are only using string comparison on license_expression values ATM, we will want to be able to compare complex expressions and their categories and score them appropriately.

For example, currently when we compare mit OR bsd-new OR mit with mit OR bsd-new, this would fail currently. With the license expression library, we would be able to compare these correctly.

Okay so basically we are going to deal here with deltas having multiple licenses and going to tokenize it down.

yes

Closing due to stagnation.
