Leading zero blocks the input

[bam]

Describe the bug Leading zero stops the input

To Reproduce

1. Open demo for Number mask
2. Type 0
3. Type any non zero other number

Expected behavior Value becomes the number from step 3.

Environment:

• OS: macOS
• Browser Chrome
• Version 91
• IMask version 6.1.0
• Framework/plugin React 16

Another one case with leading zeroes:

1. Type 2
2. Put cursor to the left
3. Type 0 (yes, it's able!)
4. Repeat 2 then 3

Result:

But input after 2 or inbetween is blocked

Seeing the same behavior.

first case is not fixed (imo on input value should be either allowed or blocked but not replaced)
