zstandard won't work with AddressSanitizer after #61

Solution to issue cannot be found in the documentation.

Issue

Adding RTLD_DEEPBIND has broken running code that depends on zstandard (and urllib3/requests by extension) together with Address Sanitizer (ASAn):

You are trying to dlopen a $CONDA_PREFIX/lib/python3.10/site-packages/zstandard/backend_c.cpython-310-x86_64-linux-gnu.so shared library with RTLD_DEEPBIND flag which is incompatible with sanitizer runtime (see google/sanitizers#611 for details). If you want to run $CONDA_PREFIX/lib/python3.10/site-packages/zstandard/backend_c.cpython-310-x86_64-linux-gnu.so library under sanitizers please remove RTLD_DEEPBIND from dlopen flags.

(As previously commented here.)

Do you have a different solution for the mentioned issue that would work with AddressSanitizer?

Sorry, not off the top of my head (I did not catch up with all details leading to #60), but I can try to brainstorm something.

Maybe #61 could be reverted, applying a different solution such as adding constraints to ensure compatible zstandard and zstd are in the env (if that makes sense)?
