* This is a tiny purpose-built HTML parser/processor. This basically detects any type of visual newline and
* allows it to be processed, useful for greentexting, mostly
*
* known issue: doesn't handle CDATA so nested CDATA might not work well
*
* @param {Object} input - input data
* @param {(string) => string} processor - function that will be called on every line
* @return {string} processed html
