Feat/refactor replace axios with fetch

[royscheeren]

Scope:

• Replace axios with native fetch
• Add option for a custom timeout

Breaking change:

When calling queryAccessControl the function now expects a single object in the form of

{
 query: {},
 allowlist: [], // optional
 options: {}, // optional
}

instead of the separate parameters query and options Fixes #27 Fixes #26
