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.
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.
