[roboticsexpert]

if you upload large file , it will eat memory ... but you can upload it as stream

also added support for laravel 7

check it and say anything would you like to change

just squash it

Sounds like a good idea, thanks!

I would appreciate it if you could:

• Remove local IDE files from git (.idea)
• Adhere to the package style, or at least nog modify (whitespace) style for existing files
• Add/update tests for changed functionality or new featurs

There's quite a bit I have to sift through here before I can consider merging.

If not, that's fine too -- I will use your changes as a base/suggestion for adding this feature. I do also want to look into the possibility of adding features without breaking changes, if possible.
