markdown: Elixir given code does not follow the specification/given documentation

[Sayrus]

The given implementation does not follow the Markdown specification nor does it follows the expected output given in the code comments. The purpose of the exercise is to refactor, after reading #271, I do think this should be fixed.

Header parsing rely on split to get the current header level:

iex(1)> Markdown.parse("#Test")
"<h5></h5>"
iex(2)> Markdown.parse("# Test")
"<h1>Test</h1>"
iex(3)> Markdown.parse("#I_am_a_very_large header")
"<h18>header</h18>"

List doesn't work any better:

iex(1)> Markdown.parse("* Test")
"<ul><li>Test</li></ul>"
iex(2)> Markdown.parse("*Test") 
"<ul><li>*Test</li></ul>"

And the real problem as the others could just be on purpose. According to the comment given in the code:

iex> Markdown.parse("#Header!\n* __Bold Item__\n* _Italic Item_")
"<h1>Header!</h1><ul><li><em>Bold Item</em></li><li><i>Italic Item</i></li></ul>"

Reality when using the ref:

iex(7)> Markdown.parse("#Header!\n* __Bold Item__\n* _Italic Item_")
"<h8></h8><ul><li><strong>Bold Item</strong></li><li><em>Italic Item</em></li></ul>"

Without performing any deeper investigating, it seems to me that this is an issue for the @exercism/elixir maintainers to look into and should be moved to the Elixer repo.

You're right, I missed this repo. I'll wait for an repo admin to move it as I don't want to create a duplicate.
