Support nulls=stripped introduced by PostgREST 11.2.0

[steve-chavez]

PostgREST 11.2.0 introduced stripping of null value properties in JSON results for arrays and single object responses. To support that functionality in postgrest-js a method like stripNulls()could be introduced. For instance: client.from('table').select().stripNulls().

Great addition. Thank you for the continuous improvement and maintenance.

My two cents: I would also like if it could be set as a global option.
