Preserve HTML element attributes in @bassetBlock

[jnoordsij]

The bassetBlock method currently removes the entire script/style block before writing contents to a file,
while it may still contain relevant information.
For example, it could be nice to allow attributes to be preserved, so one could:

• add type=module to use a module script
• add data-x attributes to easily access the element and/or query metadata from it in a structured way

Alternatively, an easier way to implement a change that would make this possible is simply adding an attributes parameter to the function, so one can leverage that to pass (custom) attributes.
