Derivation Path refactor

[tclemos]

close shttps://github.com/0xPolygon/devtools/issues/182

The topics below are applied to polycli wallet command.

• Changes the default value for --addresses from 10 to 1
• When --addresses is 1, the derivation path is the same as provided by --path
• When --addresses is greater than 1, it will use the value provided by --path to provide sequential derivation paths starting from the provided one, extended to at least five parts and evolving one by one using the last part as the start index, see examples below.

Examples:

• for --addresses 1 and:
  • --path m/44'/60'/0, generates: m/44'/60'/0
  • --path m/44'/60'/1'/0, generates: m/44'/60'/1'/0
  • --path m/44'/60'/2'/0/3, generates: m/44'/60'/2'/0/3
  • --path m/44'/60'/3'/0/7/9, generates: m/44'/60'/3'/0/7/9
• for --addresses 3 and:
  • --path m/44'/60'/0, generates: m/44'/60'/0'/0/0, m/44'/60'/0'/0/1, m/44'/60'/0'/0/2
  • --path m/44'/60'/1'/0, generates: m/44'/60'/1'/0/0, m/44'/60'/1'/0/1, m/44'/60'/1'/0/2
  • --path m/44'/60'/2'/0/3, generates: m/44'/60'/2'/0/3, m/44'/60'/2'/0/4, m/44'/60'/2'/0/5
  • --path m/44'/60'/3'/0/7/9, generates: m/44'/60'/3'/0/7/9, m/44'/60'/3'/0/7/10, m/44'/60'/3'/0/7/11
