Add other hardware wallets

[trevigol]

I suggest to add Ellipal, D'CENT and Safepal hardware wallets.

They all use m/44'/0'/0' for btc legacy address.
I don't know about the segwit address though. They all show different addresses so I guess they use a different derivation path.

I recommend asking the project devs to make a PR with accurate information
