/**
* Computes the effective certificate chain from the raw array returned by Java's built in TLS APIs.
* Cleaning a chain returns a list of certificates where the first element is {@code chain[0]}, each
* certificate is signed by the certificate that follows, and the last certificate is a trusted CA
* certificate.
*
* Use of the chain cleaner is necessary to omit unexpected certificates that aren't relevant to
* the TLS handshake and to extract the trusted CA certificate for the benefit of certificate
* pinning.
