pyln-client: to_whole_satoshi returns the rounded up satoshi value

Browse Source 
A fractional satoshi value isn't really useful; rounding up loses
precision but that's why you called "whole satoshi", wasn't it?

Changelog-Changed: pyln-client: Millisatoshi has new method, `to_whole_satoshi`; *rounds value up* to the nearest whole satoshi
