csv.lua: now that a buffer looks like a string, reading strings is easier

csv.lua: separate the buffering stuff out into a file_buffer class (that looks strangely like a string...)

csv.lua: track the buffer start with a variable called (surprisingly) buffer_start, and now field_start and line_start count from the start of the whole file, not the current state of the buffer

whoops. Fix up find's return values when we've hit the end of file. How did that work?

csv.lua: tidy up truncating the buffer (not really the right word, since we're cutting off the beginning) and advancing anchor_pos (also a bad name)

Test at all buffer sizes from 1 to 16. Fix the resulting bug when an embedded quote straddles two buffer blocks

csv.lua: this all doesn't work with small buffer sizes. Whoops. Made tests at small buffer sizes and fixed the problem

csv.lua: move some variable definitions closer to their use (the aim here is to move find and sub out into a buffer object)

Added an openstring function, by wrapping the string in an object
...
that supports read(bytes) and passing the object to the underlying
code. Modified all the tests to run with both open and openstring.
Changed the default buffer size in csv.lua to match the value in the
README, and added the crucial blank line to test-data/blankline.csv

ignore blank lines (I'm not sure this is a good thing *in* the file, but ignoring blank lines at the end is a good idea)
