castValue will return array of values when last tag has several occurrences

[BigOHenry]

When last tag has multiple occurrences, now only the first one is returned as string:

......
    <Detail>
        <DynPar>T0019:2,R0109:test2,R0108:,R0107:,T0025:X</DynPar>
        <DynPar>T0019:3,R0109:test3,R0108:,R0107:,T0025:Y</DynPar>
    </Detail>
....

Current result is only value from first tag:
'DynPar' => 'T0019:2,R0109:test2,R0108:,R0107:,T0025:X',

After this commit, it will return array of values:

'DynPar' => [
        'T0019:2,R0109:test2,R0108:,R0107:,T0025:X',
        'T0019:3,R0109:test3,R0108:,R0107:,T0025:Y',
    ],

Hey,

This resolved an issue I was having with parsing DDEX XML files, so was wondering if there was any timeline for implementation, or perhaps even a reason that it's unsuitable to be added for now.
