Issue Description
Apply face recognition on a 2 base64 string.
Steps to Reproduce
Apply face recognition using a 2 base64 string.
Expected Behavior
The API should be able to handle base64 images directly.
**Environment
macOS M1

• Module version?
  "@vladmandic/face-api": "^1.7.7"
• Built-in demo or custom code?
  Code to convert the image: const imgSourceRef = await faceapi.fetchImage(source); Where source is a base64 string. This produces the above error
• Type of module used (e.g. js, esm, esm-nobundle)?
• Browser or NodeJS and version (e.g. NodeJS 14.15 or Chrome 89)?

➜  terminal ✗ node -v 
v18.12.1

• OS and Hardware platform (e.g. Windows 10, Ubuntu Linux on x64, Android 10)?
• Packager (if any) (e.g, webpack, rollup, parcel, esbuild, etc.)?

Additional

• For installation or startup issues include your package.json
• For usage issues, it is recommended to post your code as gist

Expected Behavior
The API should be able to handle base64 images directly.

why would you expect that library should be able to handle base64 images directly?
library cannot be expected to "just know" how to handle every possible input type.
and base64 does not even contain information about image encoding - is it rgb pixel-data, or rgba, or jpeg, or png.

i'm afraid you'll have to decode it yourself before using faceapi

btw, note that fetchImage is just a wrapper around platform fetch followed by filling resulting blob to image element using FileReader - so no chance that would work even if fileReader was implemented differently for nodejs.
