This builds the CI fuzzers with the intended clang version. It also allows users to set the clang version locally, in case they need to. It also switches the CI fuzzers to use an optimized sanitizer build, to do something oss-fuzz doesn't and get more done in the short time the CI fuzzer runs.

# This script is to make a quick check that the fuzzers work,
|
|
# good when working locally developing the fuzzers or making
|

# sure code changes still pass the fuzzers.

# It will download the corpus from bintray (kept up to date
|

# by the crontab github actions) unless a local out/ directory

# already exists.
