PassThruConnect flags invalid value#287

According to SAE J2534 API reference (check https://studylib.net/doc/27193342/dokumen.site-passthru-api-1 page 6) bits 0-6 of "flags" parameter should not be used and should be zeroed. This issue can lead to problems with some J2534 interfaces:
RuntimeError: J2534 PassThruConnect: CAN_ID_BOTH and CAN_29BIT_ID are the only valid ConnectFlags (Error_ID.ERR_INVALID_FLAGS)

    I'm open to PR. I did not write the J2534 adapter, the community did

    I think this has been corrected in latest release with refactor done by @kirya-dev
