Spec length for UTF8 encoded strings seems to always be 2 characters short

[boomskats]

Pretty sure it's down to this:

h54s/src/sasData.js

Line 198 in 2021a9c

specs[key].colLength = Math.max(specs[key].colLength, colLength - 2);

It works fine when there are no multibyte characters involved. This should also solve the PROC JSON bug we've been seeing with the utf8 tests, as they've been failing when the last character has been a triple byte char split truncated by 2 bytes.

Fixed in 12f3bd4, and changed test for UTF-8. It's working now with 3-byte characters
