Support SODA API version 2.1

[bolek]

I am trying to run the following query:

def soql = new SoqlQueryBuilder()
        .addSelectPhrase("count(*)")
        .setWhereClause(":updated_at>'${dateString}'")
        .build();

soda-java currently generates the following url:

https://data.cityofnewyork.us/resource/fhrw-4uyv.json?$select=count(*)&$where=:updated_at%3E%272018-05-08T21:19:25Z%27&$$version=2.0

which returns

{"message":"Invalid SoQL query","errorCode":"query.soql.invalid","data":{}}

Seems that this particular query is not supported by API version 2.0. Changing version to 2.1 results in a successful response.

The API SODA_VERSION is set here:

soda-java/src/main/java/com/socrata/api/HttpLowLevel.java

Line 633 in 75f89c9

final UriBuilder builder = UriBuilder.fromUri(uri).queryParam(SODA_VERSION, "2.0");

Are there any plans to bump SODA_VERSION to 2.1?
