fix: removing bind and refactoring consumer

[mogu4iy]

Resolves #NUMBER

Description:

There is an inheritance issue, that it's not possible to extend Consumer class. It happens because you autoBind all propertyNames from constructor.prototype, so while extending these properties are not accessible anymore in this way.

Type of change:

• [x] Bug fix (non-breaking change which fixes an issue)
• [ ] New feature (non-breaking change which adds functionality)
• [ ] Breaking change (fix or feature that would cause existing functionality to change)

Why is this change required?:

There are cases when we what to extend Consumer class, to pass pre defined options for example. I have created minimal reproducible exaple.

Code changes:

• Add missing type declarations
• Remove autoBind usage to let extend this class
• Update passing in-class methods to intervals using arrow functions to solve context passing issue

Hey, thanks for the PR.

I'm not too sure the reasoning behind the bind, and if we need it or not honestly, it's before my time.

I'll have to have a look through this when I have a spare hour or two, bare with :).

It was used to avoid passing class methods to intervals or promise then calls using arrow functions.

Yeh it was part of the original commit years ago, so potentially just old Node/JS thoughts. I'll have a proper look through tomorrow.
