Remove TODOs from README.md

Tracking these through issues is better.

Also, `rustfmt` only needs to be called on top-level files
(see rust-lang/rustfmt#2426). It does
need to be called on every example, though, as those count as top-level
files.

Mention that signed GPG commits are preferred.

-# To do
-
-- verify use of `i64` versus `u64` in API
-- document low and high level handling
-- document error handling
-- reproducible functional test that exercises against actual lightning instances (regtest?)
-- a better way to get at the data for failed payments

-
-  `data` could be parsed into a structure, but this depends on the kind of error
-
-- the API could make more use of enums where the possible values are known; for example the
-  `addresstype` parameter to `newaddr`, but also in returned structures. This has to be weighted
-  against flexibility, though, in case the API is extended later.
-
-- decide on `&str` versus `String` on high-level API (but at least make sure it is consistent)
