* Add ReconstructData interface method to allow reconstruction of any missing data shards
* Add support for just reconstructing data shards only to SteamEncoder.Reconstruct()
PAR1 is a file format which uses a Reed-Solomon code similar
to the current one, except it uses a different (flawed) coding
matrix.
Add support for it via a WithPAR1Matrix option, so that this code
can be used to encode/decode PAR1 files. Also add the option to
existing tests, and add a test demonstrating the flaw in PAR1's
coding matrix.
Also fix an mistakenly inverted test in testOpts().
Incidentally, PAR1 is obsoleted by PAR2, which uses GF(2^16)
and tries to fix the flaw in the coding matrix; however, PAR2's
coding matrix is still flawed! The real solution is to build the
coding matrix like in this repository.

* Add options
Make constants changeable as options.
The API remains backwards compatible.
* Update documentation.
* Fix line endings
* fmt
* fmt
* Use functions for parameters.
Much neater.
