Implement a command to display info about farmer

[ozgunozerk]

Scenario: Getting information on the farmer
	Given I am farming
	When I run `subspace-cli info`
	Then I should see information on the farmer instance

The information can be the following:

• is a farmer instance active, if so, the status of that instance:
  SYNCING 40% - (process ID) connected to Gemini-2a
• how much reward they gained in total (need block explorer integration for this, let's do this later)
• how much space they pledged
• how much space is pledged in total (by the network) - check this formula https://github.com/subspace/block-vote-authorship-collector

Considering these will be available to CLI via SDK, this should be fairly easy to implement

I think we may need to revisit this and try to do a couple things:

• Echo out what we see from the SDK
• append Have CLI show reward total earned #33 and Show how much space pledge in total by network #34 on the bottom of the info
