parse

Parses dotenv content into (key, value) pairs, in file order.

Blank lines, # comments and lines that are not valid KEY=value assignments are skipped. Supported: an optional export prefix, bare values (a # after whitespace starts a comment), "double quoted" values with \n \r \t \" \\ escapes and 'single quoted' literals. Values are single-line. A key assigned twice appears twice.
