Function substrate_bip39::mini_secret_from_entropy

pub fn mini_secret_from_entropy(
    entropy: &[u8], 
    password: &str
) -> Result<MiniSecretKey, Error>

entropy should be a byte array from a correctly recovered and checksumed BIP39.

This function accepts slices of different length for different word lengths:

• 16 bytes for 12 words.
• 20 bytes for 15 words.
• 24 bytes for 18 words.
• 28 bytes for 21 words.
• 32 bytes for 24 words.

Any other length will return an error.

password is analog to BIP39 seed generation itself, with an empty string being defalt.
