CSS Local Image Reference -> Data URI Transform

Accepts a file argument and an (optional) opts argument. For a CSS file passed as input, returns a through stream with references to local images replaced by inline data URIs. All other files return a vanilla through stream.

The opts argument object may contain the following:

• maxImageSize : size (in bytes) beyond which local images references will not be converted to data URIs.

Can be used as a parcelify transform.

Draws heavily from Grunt Image Embed by Eric Hynds.

#Usage

css-img-datauri-stream(file [, opts])

• file - the CSS file to transform
• opts - optional object whose 'maxImageSize' member specifies a byte size beyond which local image references will not be converted to data URIs.
