Parse multiple HTML tags in a single line

[jonatanklosko]

Given a single line with multiple tag pairs, all except the first one are ignored:

iex> EarmarkParser.as_ast("<kbd>Ctrl</kbd>+<kbd>A</kbd>")
{:ok, [{"kbd", [], ["Ctrl"], %{verbatim: true}}], []}

The parser shouldn't drop the content, so I think we could either:

• interpret <tag>...</tag>some more content as a paragraph (this mirrors the behaviour if the same sequence was in the middle of the text)
• parse such line into multiple AST nodes, like [{"kbd", [], ["Ctrl"], %{verbatim: true}}, "+", [{"kbd", [], ["A"], %{verbatim: true}}]]

Will be fixed with #7
