Please bundle Apache 2.0 license in the releases as the license requires

[vlsi]

The license requires to give a copy of the license when redistributing the software:

See https://www.apache.org/licenses/LICENSE-2.0
4.a You must give any other recipients of the Work or Derivative Works a copy of this License; and

Even though fast_float.h in the releases includes a link to http://www.apache.org/licenses/LICENSE-2.0, the link is not a copy as the link might become inaccessible, so the recipients might fail to receive "a copy of the License".

Ideally, the full text of Apache-2.0 should be included in fast_float.h as it seems to be "single-file release artifact" (10KiB license vs 110KiB implementation).

As an alternative, it might work if you add a separate LICENSE with full Apache-2.0 text side by side with fast_float.h in the releases.

Just in case, here's the opinion of the Apache Software Foundation: https://issues.apache.org/jira/browse/LEGAL-642
