Adding the assemble_archive_from_position function into the docs

[jessicapilling]

I have added in a section to the 'Observations of Messier 51 from many telescope archives' notebook that demonstrates how to use the assemble_archive_from_position function

Hi Jess - nice work on this. I'm just going through it and I'll add any things I spot that need changing. First thing is in the writing in the introduction for the one line solution - 'excecutes'

[DavidT3]

"all available missions within DAXA, perform the" -> "all available missions within DAXA, calls the"

[DavidT3]

"return a list of filtered BaseMission objects which have observations after the filtering." <- the wording here is a little clumsy I think

[DavidT3]

I think when it comes to this bit:

"So we can finally run the assemble_archive_from_positions() function with our inputs:"

You should reiterate that if you ran it without the missions input it would just use all of them.

[DavidT3]

Maybe you should also mention the other function as well, that just searches without defining an archive, I think that will be quite useful if you're just exploring and don't want to make anything permanent yet.

I altered a couple of things, which included adding the daxa.mission.tools section that you added to the API documentation files, otherwise it wouldn't have been included (a reminder that whenever you add an entirely new sub-module or sub-module file, you need to look at the RST files and add a new section - I can demo this for you if you need!)
