Faulty parsing logic in ZScaler ASIM parsers

[uhkahaku]

Describe the bug
Latest ZScaler parsers _ASim_WebSession_ZscalerZIAV04 and _Im_WebSession_ZscalerZIAV06 use parse operation instead of parse-kv for AdditionalExtensions field. This field may not contain all properties required by the parse operation, which causes the operation to not parse anything.

Current parsing logic:

// -- Parse
| parse AdditionalExtensions with 
    * "rulelabel=" RuleName:string ";"
    "ruletype=" ruletype:string ";"
    "urlclass=" urlclass:string ";"
    "devicemodel=" * 

Using parse-kv:

// -- Parse
| parse-kv AdditionalExtensions as (rulelabel: string, ruletype: string, urlclass: string) with (kv_delimiter="=", pair_delimiter=";")

This operator is also preferred by the documentation.
