Bump version to 0.2.0

This change bumps the version of the crate to 0.2.0. The following
notable changes have been made since 0.1.3:
- Use the nitrokey crate for the 'open', 'close', and 'status'
  commands instead of directly communicating with the Nitrokey device
  - Added nitrokey version 0.2.1 as a direct dependency and
    nitrokey-sys version 3.4.1 as well as rand version 0.4.3 as
    indirect dependencies
  - Removed the hid, hidapi-sys and pkg-config dependencies
- Added the 'otp' command for working with one-time passwords
- Added the 'config' command for reading and writing the device configuration
- Added the 'pin' command for managing PINs
  - Renamed the 'clear' command to 'pin clear'
- Moved 'open' and 'close' commands as subcommands into newly introduced
  'storage' command
  - Moved printing of storage related information from 'status' command
    into new 'storage status' subcommand
- Made 'status' command work with Nitrokey Pro devices
- Enabled CI pipeline comprising code style conformance checks, linting,
  and building of the project
- Added badges indicating pipeline status, current crates.io published
  version of the crate, and minimum version of rustc required
- Fixed wrong messages in the pinentry dialog that were caused by unescaped
  spaces in a string
- Use the argparse crate to parse the command-line arguments
  - Added argparse dependency in version 0.2.2
