BIP-44 based HD wallet in mycelo

[hiromaily]

Description

For now, HD wallet derivation path is not based on BIP-44 in mycelo. This difference makes key synchronization among other libraries difficult. Proper path must be like m / purpose' / coin_type' / account' / change / address_index. This is specification.
e.g. "m/44'/60'/0'/0/0" is correct, but current"m/1/0" is not. mycelo code

For example, developer account keys are generated after running geth nodes with specific mnemonic through mycelo. Then I want to deploy contracts onto celo geth nodes. However it's difficult to generate same address with mnemonic using other libraries like @truffle/hdwallet-provider in truffle-config.json

Current Behavior

HD wallet derivation path is not based on BIP-44 in mycelo

Context

This is BIP-44 specification.

Proposed Solution

To follow bip-44, m / purpose' / coin_type' / account' / change / address_index,
only coin_type need to be fixed which value must be used in mycelo. But I'd like to pass this value when running mycelo command.
