Add support for array types

[gonzodepedro]

UI Add EditorWidgets in param_editors.py to support the following types:

• byte_array_value
• bool_array_value
• integer_array_value
• double_array_value
• string_array_value

This should be solved by #108. Please check and close.

Hi @christianrauch @gonzodepedro ,

I'm running rqt_reconfigure in humble and didn't have double arrays coming up.

#108 seems to work having patched param_editor over to my rqt_reconfigure and running nodes. Parameters dynamically changing and everything - thanks so much!

Is it possible to push this commit to not only rolling but to humble (and others I distros) as well?

[christianrauch]

I guess you have to ask in #108 if this can be backported to humble, or better, just send a PR that backports that fix.

Thanks! Have raised a PR to do this #145
