[PyWB2] Query param fl is ignored

[sebastian-nagel]

The query parameter to select the result fields (fl) is ignored by PyWB 2.3.0. As visible in the code it has been renamed from fl to fields with a fall-back for the old param name. But it does not work and furthermore causes the output param to be ignored:

Note: the old index based on pywb 0.33.2 already recognizes the param fields.
