Add support for static entropy

[dr-orlovsky]

We have to target it for v0.11 since it breaks APIs - and there is no way of adding support for the feature without the API break

Looks good but there are some warnings that may be addressed:

warning: unnecessary `pub(self)`
  --> commit_verify/src/lib.rs:48:1
   |
48 | pub(self) mod commit;
   | ^^^^^^^^^ help: remove it
   |
   = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#needless_pub_self
   = note: `#[warn(clippy::needless_pub_self)]` on by default

warning: unnecessary `pub(self)`
  --> commit_verify/src/lib.rs:51:1

   | ^^^^^^^^^ help: remove it

warning: methods with the following characteristics: (`to_*` and `self` type is `Copy`) usually take `self` by value

    = help: consider choosing a less ambiguous name
    = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#wrong_self_convention
    = note: `#[warn(clippy::wrong_self_convention)]` on by default

As said in BP-WG/bp-core#56 (comment) I think clippy should fail when there are warnings

This should help with unit testing, I would think
