Fix 143

[mvarewyck]

This PR fixes

• Allow to set start year and x-scale stepsize for indicator_native_range_year #143
• [Feature request] add option to display cumulative Number of introduced species per year and per native continent to graph inbo/alien-species-portal#119: include option to change response type to either "absolute", "relative" or "cumulative" numbers. I have therefore replaced the function argument boolean 'relative' by character 'response_type'.
  @damianooldoni should we foresee backward compatability?
• Fix duplicate filtering. It was too strict, filtering out all duplicates per year and location (max value per year was 1 per location), while it should be for year/location/key (multiple species introduced per year&location) (Fix duplicate filtering for indicator_native_range_year() #145).
• Add NEWS.md (Add NEWS.md #140)

I have increased version to 2.3.2 (not sure what are the internal guidelines about this)

Thanks @mvarewyck for the improvements of the function!
The changes as they are now are breaking code. And it means that we need to upgrade to version 3.0.0. Typically, I would reply that such changes are not worth a major version change. However, this package is not on CRAN and not widely used. So, I could say that we can upgrade to 3.0.0.

However, please consider the following changes:

• make old arguments (relative) deprecated. Set internally response_type based on the value given to relative. Please, use lifecycle::deprecated() for it. Quite self-explanatory example from camtraptor::read_camtrap_dp()
• As we go for 3.0.0, it's definitely time to start a NEWS.md from now on. Could you please add such file in root folder? Don't worry about older versions. We will start from 3.0.0. You can follow this example from camtraptor which is automatically rendered as this website.

Hi @mvarewyck 👋
Is it ok if I review this PR tomorrow morning?

Sure, ready from my side.
There are still some notes in the R CMD check, but they are related to existing code, so I ignored them.

Very nice work 👍 Thanks for adding value to this package.

I have updated your role within the package: you are an author 🎉 And so I removed the @author field in roxygen documentation of the help function. Otherwise I should do the same for all other functions where others have worked on as well. git commits history is enough to know who did what in the rare case I need to ask about the code.

For the rest, I pushed some minor changes. The commit titles should be self explicative.
If you have any question about them, please let me know.
