Fix licensing issues in source release found during 0.63.0 RC1 vote (missing NOTICE file, flamegraph.svg with CDDL-licensed JavaScript)

[alamb]

Describe the bug

During the vote on the Apache DataFusion sqlparser-rs 0.63.0 RC1 release, @Xuanwo identified two licensing-material issues in the source archive and voted -1 (non-binding): https://lists.apache.org/thread/3lnhgs0bwzl148yrdrcl5g005h9pgtmx

1. Missing NOTICE file: the source archive contains LICENSE.TXT but no NOTICE file, which ASF releases are expected to include.
2. sqlparser_bench/img/flamegraph.svg embeds third-party licensed code: the generated flamegraph embeds JavaScript from Inferno, whose upstream license is CDDL 1.0, but the archive contains no corresponding license materials.

To Reproduce

Download and unpack the 0.63.0 RC1 source archive (or check the repository at v0.63.0-rc1):

$ ls NOTICE*
ls: NOTICE*: No such file or directory

$ grep -c -i inferno sqlparser_bench/img/flamegraph.svg
2

Expected behavior

The source release complies with ASF licensing policy:

1. Add a NOTICE file to the repository so it is included in source archives.
2. Exclude the generated sqlparser_bench/img/flamegraph.svg from the source release
