Addresses #44
Description
The bigger the encoded data, the qr code tends to shrink in size to accommodate the increase in the qr code patterns required to encode it without overflowing its container size.
Hence, this PR adds a new feature for users to set their own correction level, and also recommends an appropriate correction level based on their current data length. The recommended data lengths are based off random sources of the internet.
