RUSTSEC-2020-0036: failure: failure is officially deprecated/unmaintained

[brightly-salty]

When cargo-audit is run on any project with a direct or indirect dependency on ffsend-api, the following is output (for more info, see https://rustsec.org/advisories/RUSTSEC-2020-0036):

Crate:         failure
Version:       0.1.8
Warning:       unmaintained
Title:         failure is officially deprecated/unmaintained
Date:          2020-05-02
ID:            RUSTSEC-2020-0036

Dependency tree:
failure 0.1.8
└── ffsend-api 0.6.3

It can be somewhat easily remedied by replacing with another error crate like thiserror, anyhow, or eyre.

I would be willing to attempt to implement this and submit a PR if it would be accepted

Thanks for your report. Yes, replacing this with thiserror and anyhow would be great.

Of course, that would be awesome! If you'd like to give this a try for the whole crate, go ahead.

I believe this will introduce breaking changes, as the error types are (obviously) exposed. This is fine, and we'll just release it as new minor version.

I'll probably take the work to update ffsend with these changes along side it.

Would you like to give updating ffsend a try as well (with ffsend-api v0.7.2), or should I do this myself at a later time?
