Pretty numbers (like 1`000`000)

Let allow to use pretty numbers in code.

Pattern looks like Digit_1 = d

Inner_digit = d|`

Many_digits = Digit_1(Inner_digit)*Digit_1

Digits = Digit_1|Many_digits

This numbers must be valid (and may be add to class Read):

{{{ 100000000000000000 10000000.00000005 0xFFFFFFFFFFFFFFFF 10000e1005 and this: 10000000000000``0000 but not this: 1000``` }}}
