Add functionality to encode numbers

[sarthakg043]

Right now the given emoji set is being used to encode letters from A-Z which can be found in index.py file

nature_emojis = [
    '🌿', '🌻', '🍃', '🌸', '🍂', '🌺',
    '🍀', '🍁', '🍄', '🌹', '🌲', '🌴',
    '🍅', '🍆', '🌽', '🍊', '🍎', '🍓',
    '🍑', '🍍', '🍌', '🍉', '🍇', '🍈',
    '🍐', '🍏'
]

TASK

• Increase this emoji base and encode numbers 0-9 with different emojis.

Hint

You need to modify this encrypt and decrypt functions in index.py
