RAM usage #11

Thank you for this great library. It works great but is using more than 60% of my available RAM. Is there any way to reduce the BearSSL memory usage (with compilation or linking options, removing some BearSSL source code ...etc)?

it looks like I can change BearSSLClient _iobuf[8192 + 85 + 325] to _iobuf[1024 + 85 + 325] to save 7K RAM usage.
