chore: release 0.10.0 (#282)

Removed the zzz-release tool.  It's a great idea, but its logic isn't specific to the rust agent,
and would be better maintained as an independent project.

Set all crate versions to 0.10.0

+## [Unreleased]
+
+## [0.10.0] - 2021-11-15
+
+Unified all version numbers and removed the zzz-release tool.
+
+### ic-agent
+
+#### Fixed: rewrite all *.ic0.app domains to ic0.app to avoid redirects.
+
+### icx-cert
+
+#### New feature: Add --accept-encoding parameter
+
+It's now possible to specify which encodings will be accepted.  The default (and previous) behavior
+is to accept only the identity encoding.  Specifying encodings that browsers more commonly accept
+demonstrates the difference in the returned data and certificate.
+
+For example, here is the data and certificate returned when only accepting the identity encoding.
+
+```
+$ cargo run -p icx-cert -- print 'http://localhost:8000/index.js?canisterId=ryjl3-tyaaa-aaaaa-aaaba-cai'
+DATA HASH: 1495cd574831c23b4db97bc3860666ea495386f0ef0dab73c23ef31db5aa2765
+    Label("/index.js", Leaf(0x1495cd574831c23b4db97bc3860666ea495386f0ef0dab73c23ef31db5aa2765)),
+```
+
+Here is an example accepting the gzip encoding (as most browsers do), showing that the canister
+responded with different data having a different data hash.
+
+```
+$ cargo run -p icx-cert -- print --accept-encoding gzip 'http://localhost:8000/index.js?canisterId=ryjl3-tyaaa-aaaaa-aaaba-cai'
+DATA HASH: 1770e76af0816ba951320c03eab1263c43de7ac4b0558dd9049cc532b7d6cd01
+    Label("/index.js", Leaf(0x1495cd574831c23b4db97bc3860666ea495386f0ef0dab73c23ef31db5aa2765)),
+```
