No 'Bip49Coins' in bip_utils
In the examples given in the documentation:
https://pypi.org/project/bip-utils/
it is shown in a table that different coins can be selected for Bip49 just like with Bip44. 
With Bip44 everything works as expected. However, there is however no `Bip49Coins ` in bip_utils.
I did notice there is a `Bip49Coin`, so without the 's' at the end, but this does not contain coins you can select.

I made sure to upgrad to bip_utils-1.11.1.
