Shared images through TikTokShareRequest are in a wrong order #15

Hello there.

When I share multiple images through a TikTokShareRequest to have a carousel post on TikTok, the order of the images matching the supplied local asset identifiers is not kept. From what I've seen so far, it seems that images in the final carousel are in the alphabetical order of their local asset identifiers. For example, if I have this array of identifiers: 

[
  "CB651F89-58DB-422D-8A55-CCCA3DA26310/L0/001", // Image 1
  "1C47D10E-4734-4B9F-A575-E40BC4AB3CB3/L0/001", // Image 2
  "26DBD447-6846-4CC7-AFEA-775DCE63EF90/L0/001" // Image 3
]

and pass it to a share request like so:

TikTokShareRequest(localIdentifiers: identifiers, mediaType: .image, redirectURI: <my_url>)

The images will appear inside the carousel in the TikTok app in this order:

[
  "1C47D10E-4734-4B9F-A575-E40BC4AB3CB3/L0/001", // Image 2
  "26DBD447-6846-4CC7-AFEA-775DCE63EF90/L0/001" // Image 3
  "CB651F89-58DB-422D-8A55-CCCA3DA26310/L0/001", // Image 1
]

The bug seems to be on TikTok app side, as the identifiers are still in the right order inside the deeplink launching it:

Hi @zepojo , I found the cause for this issue. The fix for it will be available in TikTok version 31.8.0
