Remove @types/cytoscape dependency

[pshurygin]

The latest library version contains a dependency on the @types/cytoscape package, but the latest versions of cytoscape have native types built-in and @types/cytoscape is effectively deprecated.

The problem is, when installing cytoscape-layers we also get @types/cytoscape automatically pulled into our project, and those types mess up with the proper types from the cytoscape package.

To Reproduce

1. npm i cytoscape-layers & npm i cytoscape
2. import cy from cytoscape in the typescript context
3. See the types being used - they come from @types/cytoscape instead of cytoscape

Expected behavior

Dependency on @types/cytoscape should be removed, and peer dependency on the cytoscape package should be updated to the minimum of 3.31.
