Public repo made to test an ExpoCamera barcode scanning issue

Issue

To reproduce the problem, scan with Expo Camera a type-39 barcode with consecutive identical digits. Example ERUUUUU3.

https://barcode.tec-it.com/en/Code39?data=ERUUUUU3

onBarCodeScanned data result is randomly :

• ERUUUUU3
• ERUUUU3
• ERUUU3.

This only happens when a barcode with identical consecutive numbers is scanned; a barcode like ER123456 works perfectly.

Tested this barcode(ERUUUUU3) with zxing-js library and there is no problem ( on this testing web page https://zxing-js.github.io/library/examples/multi-camera/ )
