credentials not implemented for fetch in some environments such as cfw

[einkoro]

When trying to use redaxios on CloudFlare Workers it will throw the following error:

 The 'credentials' field on 'RequestInitializerDict' is not implemented.

As the default is same-origin for credentials this could probably be worked around by not passing a credentials property when withCredentials is set to false:

In case you do not use this field and want a patch to make it go:

diff --git a/node_modules/redaxios/src/index.js b/node_modules/redaxios/src/index.js
index cca6534..a630e9a 100644

CloudFlare should really not be throwing here.
