Summary

This pull request creates a Java function that performs lossless compression on an image by integrating Tinypng and KrakenIO API.

image and provider are recieved from the payload, where image is a base64 encoded string and provider is either tinypng or krakenio

Example input:

{
  "provider": "tinypng",
  "image": "iVBORw0KGgoAAAANSUhEUgAAACAAAAAgCAYAAABzenr0AAAACXBIWXMAAAsTAAALEwEAmpwYAAAAf0lEQVR4nO2Wuw2AMAxEbw1gpMwDDMBcGQpooDKydGVAoXCK6J7k6qyc83MCCFGP/Yz+CkDF4KHmjgowbQF0CKFrCDUiwztqxabHCL0/xwcNhoI2UdsjC8g0mQvaSs1zwkg0uQAsAEaGm9/UPCeU7eMj6loTEpf6ZOQWMxd98gAhZnS6XEZcNQAAAABJRU5ErkJggg==",

}

krakenio is also a supported provider

Example output:

{
    "success": true,
    "image": "iVBORw0KGgoAAAANSUhEUgAAACAAAAAgBAMAAACBVGfHAAAAG1BMVEUAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAACUUeIgAAAACHRSTlMA8712Sxr5g97cFtUAAAA9SURBVCjPY6Aa6AADfAIcDSA8KoBTgLGVgSFCAEmAqZmBwUIBSYClzTQ4wwE52Cs6OtpR4oFFUciBerEKAP58HnyLtZsYAAAAAElFTkSuQmCC"
}

README.md contains instructions on how to run the main function.
