Feature request: Drop isomorphic-fetch from implementation

[PSoltes]

• Node 16 is no longer maintained
• Node 18 onwards includes fetch by default.
• Thus isomorphic-fetch should be replaced by plain fetch (either from browser or node)

Benefits

• significant reduction in bundle size as isomorphic-fetch uses node-fetch which is not smallest (2.6.1 version)[https://www.npmjs.com/package/node-fetch/v/2.6.1]
• isomorphic-fetch is no longer maintained
