Dynamic Attributes (#190)
* Move directories for ast tests to match convention

* feat!: Rename `:let` to `:let!`

We use the "bang" style as the reserved keyword to differentiate it from
other possible attributes.

* feat: use Phoenix.HTML as the default engine

I am choosing to leverage this library in order to quickly get dynamic
attributes (see #183) up and running.

This also ensures that folks who wish to use Temple outside of a Phoenix
project with get some nice HTML functions as well as properly escaped
HTML out of the box.

This can be made optional if Temple becomes decoupled from the render
and it including HTML specific packages becomes a strange.

* feat: Allow user to make their own Component module

The component module is essentially to defer compiling functions that the
user might not need. The component, render_slot, and inner_block functions
are only mean to be used when there isn't another implementation.

In the case of a LiveView application, LiveView is providing the
component runtime implementation. This was causing some compile time
warnings for temple, because it was using the LiveView engine at compile
time (for Temple, not the user's application) and LiveView hadn't been
compiled or loaded.

So, now we defer this to the user to make their own module and import it
where necessary.

* feat: Pass dynamic attributes with the :rest! attribute

The :rest! attribute can be used to pass in a dynamic list of attributes
to be mixed into the static ones at runtime.

Since this cannot be properly escaped by any engine, we have to mark it
as safe and then allow the function to escape it for us. I decided to
leverage the `attributes_escape/1` function from `phoenix_html`. There
isn't really any point in making my own version of this or vendoring it.

Now you can also pass a variable as the attributes as well if you only
want to pass through attributes from a calling component.

The :rest! attribute also works with components, allowing you to pass
a dynamic list of args into them.

Fixes #183
