near-cli-rs 0.2.1

There are no breaking changes in this release.

New features:

• Accounts can now be imported by simply specifying a seed-phrase or a private key (near-cli-rs will just record the private key in the key storage)
• The actions that require sending a transaction can now sign the transaction by providing a seed-phrase (it is not getting recorded anywhere) or a JSON file with a private key corresponding to the signer account id
• Interactive mode is now even better! You can also quit from CLI interactive mode by pressing Esc key
