Additional check needed before using the `in` operator for CustomEvent.detail

[Vinícius Alves]

Describe the bug

Hi, the mask crashes when CustomEvent.detail is a number, the if bellow assumes that CustomEvent.detail is always null or an object, but since it's a CustomEvent, it can have anything in the detail property.

maska/src/mask-input.ts

Line 93 in b8a2fe8

 'masked' in e.detail 

Need to check if CustomEvent.detail is an object|array before using the in operator, or it will crash when it's something else.

Steps to reproduce

Try to fill this input, it will crash the mask:
