Added example to demonstrate use georadius.

[mr-shitij]

According to standards and as used in redis server we always specify latitude first and then longitude. That's why geofilter is not working in redisearch-go client. I Fixed that bug by changing their position and also added an example to demonstrate how to use geofilter filter in redisearch-go client.

I hope you will consider.

@mr-shitij GEOFILTER is expressed as long,lat as clearly stated on docs:

GEOFILTER {geo_field} {lon} {lat} {radius} m|km|mi|ft : If set, we filter the results to a given radius from lon and lat. Radius is given as a number and units. See GEORADIUS for more details.

Same applies to the redis GEORADIUS command:

GEORADIUS key longitude latitude radius m|km|ft|mi [WITHCOORD] [WITHDIST] [WITHHASH] [COUNT count [ANY]] [ASC|DESC] [STORE key] [STOREDIST key]

Noneteless I'll fix your example, add another godoc example to make it clear.

@mr-shitij notice I've updated your PR given there was no real bug on the client. I made usage of your example and fixed it. Also included the godoc variant so that people seeing our docs can check It.
Thank you for the PR. Merging!
