Issue:
Package license files in `crates.io`
As a followup to https://github.com/tokio-rs/prost/pull/1036, it would be good to include the top-level `LICENSE` file in the `crates.io` archive for downstream packagers to use.


Discussion / hints:

Fix patch:
diff --git a/prost/LICENSE b/prost/LICENSE
new file mode 120000
index 000000000..ea5b60640
--- /dev/null
+++ b/prost/LICENSE
@@ -0,0 +1,1 @@
+../LICENSE
\ No newline at end of file
