Add a setup script

[LDannijs]

Summary

At the moment, users are required to create a bunch of files containing boilerplate code that they then need to edit whenever they want to add a vendor or new devices. This PR add 2 scripts that create all of the files by just entering a few questions. I'd like to receive feedback on what other changes could be made to improve it.

This is an in between feature, idea is that eventually a type of form will be used for the repo, but for now this should at least be helpful.

(recreated this PR cause i had some organizing of my fork)

Changes

• add 2 scripts. one for vendor + devices and one for just devices.

Preview of what the scripts look like.

@johanstokking can you take a look to @LDannijs work here

[LDannijs]

Decided to make it even easier by just compacting it all down to 1 script with a selection menu. Preview:

[LDannijs]

1. Add line breaks before 80 characters (that is the max line length)

Would I need to do this for only the echo commands or the entire code?

[johanstokking]

Ideally both but certainly anything printed.

[LDannijs]

I hope the NO_COLOR variable is properly implemented. It doesnt seem to be that standardized so I hope this is good.

@Jaime-Trinidad did you test this locally?

[Jaime-Trinidad]

Yes, there are some fixes to do:

Codec: Just fill uplinkDecoder with the decoder file name, few device makers fill downlinkEncoder and downlinkDecoder and they won't notice and cause errors.

Profile: Same can we leave macVersion empty it fills with 1.0.3 some of them may think it is ok and won't change it, so they probably don't autofill the info.

Index: @LDannijs check because I added from an existing vendor and it deletes the already info:

(apologies for messing up the commit history. There were commits from a different branch that i had accidentally been using on here, so i tried to fix it 😓. Need to learn to double check these things)

[LDannijs]

So few changes made:

• Left macVersion empty and removed downlinkEncoder and downlinkDecoder
• Made sure the index file in a company folder isn't overwritten if devices already exist in it.
• Added a check for the vendorProfileID so it increments properly.
• Also added a check if there is an available company id in the main index.yaml file.

[johanstokking]

Please ping @Jaime-Trinidad to review and test.

[LDannijs]

Did a few things:

• use bash instead of shell for better compatibility (linux especially)
• removed vendorProfileID check and creation (because it will be replaced with vendorIDs in #736, so wait with pushing this PR until that one is done)
• make sure device name is at least 3 characters long to comply with validation
• Add profile creation step to let user decide which ones they want to add.
• check the index.yaml file of a vendor to make sure a device with the same name isnt overwritten when adding a new one @Jaime-Trinidad

[LDannijs]

Turned the command to run the script into a make command to match the other commands.

And with #736 now being merged i can reopen this PR.
