defaultProps deprecation warning

[aaroncraigongithub]

Describe the bug
The following warning appears in the console when using SlidingSidePanel:

 SlidingPanel: Support for defaultProps will be removed from function components in a future major release. Use JavaScript default parameters instead.

To Reproduce
AFAIK, this is common across any use of the tool.

Expected behavior
The use of defaultProps in src/index.tsx needs to be replaced with default parameters, instead.

Screenshots
n/a

Desktop (please complete the following information):
n/a -- this is a React compatibility issue

Smartphone (please complete the following information):

Additional context

I will open a PR for this shortly.

Thank you
