The registry data uses a delimiter-separated format (AKA "CSV"). However, the custom parser used with this file also
allows empty lines and comments.
Previously the registry file contained various comments, but on evaluation none of these contained any information of
value.
The file also contained various blank lines, mostly randomly sprinkled through the file. Even the ones that were
intended to break the file into logical sections at the time when it was manually maintained were largely meaningless
due to the fact that the automated system used now always appends new entries to the end of the file.
These divergences from a pure delimiter-separated data format made it inconvenient to use the registry file with tools
that support working with standardized delimiter-separated data.
Since the divergent content didn't provide any value and instead only cluttered up the file and made maintenance more
difficult, it is hereby removed.
The library's readme describes it as follows:
> Just an example of what it takes to provide an Arduino library. This is not meant to be a serious implementation.
Libraries should only be registered if the library maintainer believes they may be of value to the Arduino community.
Registration of a library that is not expected to be of value to the community is pointless, and irresponsible since it
pollutes the Library Manager listings and increases the burden on the Library Registry maintainers.
There has only been one commit to the library in the last eight years, and that commit only added a comment, three years
ago. So there isn't any indication that the library's status can be expected to change.
It seems that a compliant release of this library was never created, meaning that although there is a registry entry,
the library is not actually listed in the libraries index.
The registration occurred eight years ago and the repository has since either been deleted or made private, so a release
of the library will never come. Thus, removing the registration will not cause any harm.
The existence of this "ghost registration" is problematic because the duplicate name check system uses the libraries
index. Since the library is not present there, the check doesn't see that the name "RGBLED" has already been registered
and thus will allow registration of additional libraries with that name. In addition, its presence may cause confusion
to the registry maintainers since we expect each registration to have a unique name.
Since the registration of the library provides no benefit and causes harm, it is removed.
