Exponantial filter refactoring

[silanus23]

I have tried to solve the issue on #365. Tried to go with the way of low_pass_filter:

• Added support both std::vector<double> and geometry_msgs::msg::WrenchStamped.
• Created a header in control_toolbox and making it use control_filters header.
• Expanded tests in a way that it tests all data types and their results in the new style.

@christophfroehlich Sorry for late response uncontrollabe delay. I copied the low_pass_filter structure. Seems like those specializations are unnecessary . Thanks for the review!

[christophfroehlich]

no worries, thanks for coming back on this. I have removed the specialization in the master branch already, have a look.

[christophfroehlich]

@silanus23 what do you think about my last comment? can we go on with this PR?

[silanus23]

@christophfroehlich I am going to try them but couldn't find time now. Won't take long to come back I guess.

[silanus23]

@christophfroehlich sorry for late update. I had to include that cause it didn't compile otherwise.
