Adjust local include policy

Add required header

Improve error handling in seek; clear eof bit after eof reached on read, so that subsequent seek doesn't fail (this is C++-standard-dependent, I learn)

Flush after write, in case we are reading elsewhere

Avoid compiler warning

Make extensionless filenames explicitly supported in wav format, for both reading and writing

Fix frame count in Opus reader

Add seek support to certain readers

Docs and build fixes

Fix occasional early EOF on WAV files read through CoreAudio

Avoid divide-by-zero if no channels found

Avoid triggering assertion failure in ope_encoder_drain when closing having written an empty output file

Further build fix

Build fixes for namespace

Remove "using namespace std" throughout. Because the various stream sources are included into a single file, an instance of this in an earlier file can interfere with system headers included in a later one (as happens with Windows and std::byte).

Don't print errors as well as returning them

Pick up frame count
