Fails to compile with current nightly

[dignifiedquire]

• rustc --version rustc 1.44.0-nightly (94d346360 2020-04-09)

Likely a bug in the nightly compiler, but maybe already known here? All working fine on 1.42.

   Compiling typed-html v0.2.2 (/Users/dignifiedquire/opensource/typed-html/typed-html)
error: overflow representing the type `std::option::Option<&T>`

error: aborting due to previous error

error: could not compile `typed-html`.

I'm reported this as a Rust error at rust-lang/rust#71359.

The current workaround (and possibly acceptable solution to be applied here) is to increase the recursion limit of typed-html to 130 (or 256 right away).

The vec reimplementation of the offending Event interator (in #117) appears to achieve the same; applying either makes things buildable in nightly.

I went with #117, which should scale better.
