Expose filtering fields with null values from Raw

[thorkildcognite]

This exposes the query parameter to control whether Raw should return fields where the value is null or not. After several failed tries, it does this through the RawRows constructor, as this is also relevant for clients that do not filter the output (so it can't just be part of RawRowsFilter, sadly). The filter is simply not a query filter, like the other components of RawRowsFilter.

Unsure if it's better to put parameter on resource client or on each call, but that'd be ok to change later
Always passing the parameter to url sounds ok too, so sdk isn't relying on possibly changing service defaults

It got fugly, since the logic to handle resource client setup is reused across databases, tables and rows, and this is only applicable for rows.

So after trying to make it pretty, I broke down and added it to the constructor and then to the baseUrl (the latter we did already with filters). I first put it into the RawRowFilter, but that didn't work for the list() call.
