Update of muon showers line after retraining the BDT with HLT1_filtered data

Retraining of the BDT for the muon detector showers line Hlt2QEE_MDS_BDT_nHits with HLT1 filtered data to solve MC/data differences.

We tried to maintain reasonable bandwidth levels without the current prescale of the Hlt2QEE_MDS_BDT_nHits line (0.01) with two distinct processing lines:

• Full-stream – for background studies (a higher cut on the BDT was imposed).
• Turbo – to ensure signal retention if the full-stream cut is too high.

This merge request is associated with the approval of Update of muon-showers weights, which updates the BDT weights after retraining with HLT1-filtered data.

BANDWIDTH TESTS:

We conducted the QEE bandwidth test using 10.000 HLT1-filtered events for the following branches:

• qee_upgrade (old muon_showers line with a 0.01 prescale)

    -  Turbo bandwidth: 191.952 MB
    -  Full-stream bandwidth: 516.516 MB
    -  Rate: 516.0 kHz

• muon_showers (new Turbo and full-stream lines with no prescale):

    - Turbo bandwidth: 158.412 MB
    - Full-stream bandwidth: 523.74 MB
    - Turbo rate: 258.0 kHz
    - Full-stream rate: 129.0 kHz
