Updated Tiled to 0.2.0, Dash to 2.18.1 and fix annotation export issue

[Wiebke]

This PR performs several maintenance updates and fixes:

• Upgrade Tiled to 0.2.0
  No code changes needed as functions for retrieving data and writing arrays have the same signature

• Upgrade Dash to 2.18.1
  This is the final release of Dash v2. The update restores the ability to delete shapes (see Dash version needs to be > 2.12.0 #205), but also reintroduces the issue where annotations disappear on resize. This strongly points to the introduction of deleteActiveShape having something to do with annotations disappearing on resizing.

• Fix annotation writing error due to missing export directory
  If EXPORT_FILE_PATH points to a directory that doesn't yet exist, the application will fail to write annotations.

These changes look good to me. I haven't tested it yet, but I was wondering if we should add the master docker compose file to this PR with the accompanying change of tiled version? So we can archive mlex_tomo_framework

Sure, that sounds like a good idea. I was working on compose improvements here for the moment: https://github.com/mlexchange/mlex_tomo_framework/tree/compose-improvements

Deferring the docker-compose.yml to a later PR.

Hi @Wiebke, may I ask whether the compose-improvements branch (https://github.com/mlexchange/mlex_tomo_framework/tree/compose-improvements) needs to be merged to stay compatible with the current main branch?
