Fix #620: remove problematic base64 encoded images

[Basssiiie]

Hello,

This PR should fix issue #620 we submitted earlier this year and should make the image cropper more compatible with a stricter Content Security Policy. It removes all problematic hardcoded usages of base64/data: urls and replaces them with permitted alternatives.

If there are any questions, feel free to ask. Thank you for your time! 🙂

Hi

That's indeed a good solution to work around the base64 issue.
Instead of parsing the base64 string and converting it to a byte array in code each time, can't the Blob be created from an int array that is provided? Like that it doesn't have to process that string every time.

@Mawi137 Thanks for the quick reply. I have moved the blob creation around the initial array. I've tested it as well and it all seems to work properly. 🙂

Hey @Mawi137, hope you had a happy holidays and pleasant new year. Have you had a chance yet to look at the updated chances, by any chance?

Looking forward to hearing from you and thank you for your time. 🙂

Happy new year to you too ;)
Sorry for the wait, I'll create a new release with this.
