backport of LHEmttFilter for 10_6

[agrohsje]

PR description/backport info:

This PR is a backport of the LHE mttbar filter to 10_6. It is needed for UL EFT MC samples.

PR validation:

I verified that the code works properly in 10_6. Generating a few events and plotting mttbar all looked good.

Sorry to have missed it for 10_6_41...

[cmsbuild]

This pull request is fully signed and it will be integrated in one of the next CMSSW_10_6_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_14_1_X is complete. This pull request will now be reviewed by the release team before it's merged. @antoniovilela, @rappoccio, @sextonkennedy (and backports should be raised in the release meeting by the corresponding L2)
