Feature/Enhancement Request: update tool functions to accept `sigflags: int|str`

[k98kurz]

Feature or Enhancement?

• ( ) New feature
• (x) Enhancement of existing feature

Description

Many tool functions have a sigflags argument, and they all expect a hexadecimal str. It should accept an int between 0 and 255 as an option and do some conversion to get a consistent type with validated data.
