Upgrade to Serde 1.0+

Upgrade from Serde 0.9.* to Serde 1.0.2. Still waiting on a release of serde-protobuf to be able to publish.

Remove force logic

I no longer try to brute-force decode a message. If it can't be decoded, it exits. Fail fast and rely on the emitter to give you correct protobufs.

If I take too many liberties with how I decode, I end up completely outputting incorrect things.

Handle tty, re-add infile argument

Handles being in a tty with no pipes. Re-added the infile positional argument.

Remove input file as argument

<input> is no longer a positional argument. Just use the pipe <myfile. Simplifies thing. Also fix a bug where --trail wasn't working, rework the trail strategy.

Stream with trailing delimiter

Add an optional --trail="string" argument to delete trailing delimiter characters.

This should make pq friendlier with input sources that output their own delimiters between each varint-delimited protobuf message.

Better errors

Better error messages.

Remove force flag

Force is no longer toggleable. Makes pqrs simpler and it shouldn't change the behavior for most usecases.

Change FDSETS_PATH -> FDSET_PATH

Misnamed env variable compared to the docs. FDSET_PATH sounds better.

Cleaner command-line options

Better manpage, moved --fdsets-path to env var $FDSETS_PATH.

Streaming

Pqrs now supports streaming (varint32 length delimiting).
