v5.5.4 - security update

Main update in 5.5.4

• Fix resilience to bogus peers by @ikatson in #106

There was a bug in rqbit where it didn't check hashes after downloading pieces. It was a one line fix, but took a long to debug. This manifested in super rare cases where after restarting rqbit, it would initialize already downloaded torrents to 99.*% and then would redownload broken pieces.

What's Changed

• A couple renames and cleanups in buffers crate by @ikatson in #101
• A few small tweaks and cleanups by @ikatson in #103
• Fix ETA computation - fixes #92 by @ikatson in #104
• Remove sha1 extra features by @ikatson in #105
