Fix: split indexing [Fixes #12]

[pataraco]

When specifying an index to the split() function, the entire list of split items would be returned.

Example/snippet serverless.yaml

custom:
  moniker: "ABCD-DEV-USWEST2"
  moniker_split: ${split(${self:custom.adsk_moniker,'-'})}
  moniker_name: ${split(${self:custom.adsk_moniker,'-',0})}
  moniker_env: ${split(${self:custom.adsk_moniker,'-',1})}
  moniker_region: ${split(${self:custom.adsk_moniker,'-',2})}

Bug:

$ npx sls print -s dev --path custom
moniker: ABCD-DEV-USWEST2
moniker_split:
  - ABCD
  - DEV
  - USWEST2
moniker_name:
  - ABCD
  - DEV
  - USWEST2
moniker_env:
  - ABCD
  - DEV
  - USWEST2
moniker_region:
  - ABCD
  - DEV
  - USWEST2

Fix:

$ npx sls print -s dev --path custom
moniker: ABCD-DEV-USWEST2
moniker_split:
  - ABCD
  - DEV
  - USWEST2
moniker_name: ABCD
moniker_env: DEV
moniker_region: USWEST2

Fixes #12

Hey @icarus-sullivan , @ymulenll and/or @peter604 !

Any hopes of getting this PR approved/merged and the npm package updated?
I didn't realize that this plugin hasn't really been maintained in a while before I started using it in our org.
And now it would be great to have this fix! 🙏

Also, if you're open to it, I'll add a replace() function 😁

Thanks guys!
