Reworks the graphics of the NFC-Tag reading process of spool and location tags. Introduces progress bar for reading process. Also first re-work of the spoolman availability (not fixed completly yet). Also fixes an issue where the API request to spoolman and octoprint was sent in parallel. This now happens sequentially to reduce heap load.
Reworks the graphics during the startup. Introduces a progress bar to visualize how much of the boot is completed. Also changes the the optics of the bambu, spoolman and wifi icons. They are now always displayed but they will be striked out if not working and they will start blinking. Also removes some unnessesary waits.
Fixes multiple potential memory leaks in API and NFC. Also fixes an issue in the new locaiton tag feature that could lead to multiple parallel API requests. This could cause memory leak issues but also result in wrong weights being registered for a spool.
Location tags can be written via the website. If a location tag is read after reading a spool tag, the location of the spool will be updated in spoolman to the location from the tag.
Fixes memory underflow when reading tags. Reads tags with their actual data size and uses actual size instead of constnat value for tag size when writing a tag.
