Remove usage of Number constructor

[dapplion]

The Number constructor is very unsafe because:

• It takes any as parameter. If we change from passing a string to Number to some object Typescript will compile and we'll get NaN.

If you do a text search of the Number constructor there are many occurrences:

• If Number arg is already an argument, remove
• If Number arg is a string, use parseInt()
• If Number arg is a bigint, use a custom util that types like bigintToNumber(bn: bigint): number

If the input of any of those functions is un-trusted data, verify the return is not NaN
