Child array recursion limited

[Jiab77]

During my internal testing, it seems to fail when "html":"[]" contains more than 2 elements... 🤔

Received:
 {"<>":"div","class":"${class}", "id":"${id}","html":[{"<>":"img", "src":"${src}","alt":"${alt}"},{"<>":"p","text":"Hi ${name}! Welcome to json2html!"},{"<>":"p","text":"Awesome it works!"}]}
Traceback (most recent call last):
