Develop a 'server version' of STATUS

[sr-gi]

STATUS was developed having in mind that any kind of computer may be able to run it (even low RAM laptops), since we wanted to allow any user to run analysis over the UTXO set, no matter their hardware capabilities.

However, such design decision makes STATUS work using temporary json files, which slow down the whole analysis process (due to I/O and having to dump/load from json). Therefore, a server version able to run storing all the intermediate values in memory will be quite useful to speed up analysis process.
