[ATR-30554] Add protection to TAPIS against having string-encoded HLT prescales
Adds an explicit cast to be able to parse the following entry with a string-encoded HLT prescale
"HLT_j20_0eta290_020jvt_boffperf_pf_ftf_L1jJ30": {
"hash": 3425380520,
"prescale": "909.09",
"enabled": true
},
which comes from https://atlas-triggertool.web.cern.ch/db/run3/smk/3393/hltpsk/11710/?name=HLT_j20_0eta290_020jvt_boffperf_pf_ftf_L1jJ30
This string-encoding is seen for the first time in the 2024 GRL.
More follow-up in the linked JIRA.
