Add support for command `GEOSEARCHSTORE`

[arpitbbhayani]

Add support for the GEOSEARCHSTORE command in DiceDB similar to the GEOSEARCHSTORE command in Redis. Please refer to the following commit in Redis to understand the implementation specifics - source.

Write unit and integration tests for the command referring to the tests written in the Redis codebase 7.2.5. For integration tests, you can refer to the tests folder. Note: they have used TCL for the test suite, and we need to port that to our way of writing integration tests using the relevant helper methods. Please refer to our tests directory.

For the command, benchmark the code and measure the time taken and memory allocs using benchmem and try to keep them to the bare minimum.

I am working on this issue. I am waiting for other GEO commands like GEORADIUS and GEORADIUSBYMEMEBER_RO to be merged as many of those functions are used in this command.
