[Feature Request] Allow filtering for access modifier

[Falco20019]

Is your feature request related to a problem? Please describe.
I have includePrivateMembers enabled since I need private methods. But I need to hide private fields.

Describe the solution you'd like
Allow filtering in a filter config like this:

apiRules:
- exclude:
    uidRegex: .*
    accessModifier: private
    type: Field

Describe alternatives you've considered
Disabling includePrivateMembers is not possible since I need the methods. The only alternative I was able to come up with is creating an attribute and marking every single private field with it.

Another workaround that works in my case is applying the filter like this (but relying on the naming scheme):

apiRules:
- exclude:
    uidRegex: \._[^\.]*$
    type: Field
