Default options not used by default

[bhb]

Version: 2.0.1

I believe that options are not passed to the parser by default i.e. this code

bai2/lib/bai2.rb

Lines 35 to 36 in 9b5d781

	@options = DEFAULT_OPTIONS.merge(options)
	parse(raw, options)

should potentially look like

 @options = DEFAULT_OPTIONS.merge(options) 
 parse(raw, @options) 

Repro:

1. Add puts "--- options #{options.inspect}" at the top of Bai2::Parser.parse`

   bai2/lib/bai2/parser.rb

   Line 29 in 9b5d781

   def parse(data, options)

2. Run Bai2::BaiFile.new(str)

Expected: Options should be the default set of options
Actual: Options are the empty hash
