v8 update

[jadeddelta]

this PR closes #138, focusing broadly on updating most (self paced reading is being completely reworked) plugins to jspsych v8, which necessitates breaking changes for all plugins as certain features handled by the core package like clearing timers/displays are left to the core package itself, along with certain plugins such as the audio plugins and plugins with button_html-esque fields being updated.

in order to improve developer experience, some plugins have added documentation where it was missing beforehand.

while all plugins function in v8, to move this PR off of draft and into merge consideration, there are several final passes and one blocking issue to content with:

• final pass on documentation, making sure all parameters and data are documented
• clarification on ParameterType.COMPLEX data types, specifically listing and documenting nested variables
• changelog everything
• this pr for letting json files be imported as modules, so that we can...
• link package.json versioning to plugin info versioning
