* Allow cargo-deny to be used as a cargo plugin

Closes: #10

* Fix binary_search for wildcards

There was a flaw in the binary search
due to how wildcards are sorted.

Also fix issue where detecting a denied
crate wouldn't actually result in a check
failure.

Add more tests for the binary_search

Resolves: #12

* Release 0.2.6

* Rustfmt

* Replace cargo-deny with cargo deny [ci skip]

* Fixup self-check

Fix the casing of the Code of Conduct link in the Contributing Guide

* Update dependencies.

* Add "LLVM-exception" to license allow list.

We currently parse out exceptions as separate licenses, which may not be the correct thing to do
Example: `wasi` crate uses "Apache-2.0 WITH LLVM-exception" as on of the licenses

For now added this case to our allow list herer but may want to reconsider how to handle it:  #22

* Allow duplicate syn/proc-macro crates

* Giant refactor of everything
* Replace slog with fern

Due to the changes to how errors are reported
and just the general user facing aspect of this tool, it doesn't really make sense to
have structured logging for cargo-deny

* Update ban check

Follows similar reporting to the license check

* Remove non-required licenses
* Add CHANGELOG
* Add 01_allow_license
* Add 02_deny_license
* Update to spdx 0.2.0
* Add hide-inclusion-graph option
* Add help for why a license is accepted
* Nuke travis
* Replace mergify with github action
* Add publish check
