Title: Allows specs to be an array of (optionally colon-delimited) values

Allow argument to extract_marc (actually, parse_string_spec) to take an array or strings. Also relaxes the colon-delimited requirement to allow spaces around the colons.

This will allow stuff like the following:

```ruby
to_field 'foo', extract_marc %w(
245abcde
810
700|*4|bcd
)

to_field('bar'), extract_marc %w(
245abcde
100:110:111
810
700|*4|bcd
)

```
