Dynamic chunk size for uploads

[pixtron]

Describe the change

Dynamic chunk size

Current situation

Chunks have a static size.

Should

• Set a max. chunk size.
• measure time for each chunk
• set chunk size for next chunk based on the time the previous chunk needed
• chunk size should always be a multiply of 512b
• if request times out (Http Status: 504), upload failing chunk with a decreased chunk size
• server has a timeout of 5 minutes

[raffis]

Starting with balloon v2.7 the chunksize must always be a multiplication of 64bytes.

Or just do not chunk at all, using the new /api/v3/sessions coming in balloon v3 you may just stream the entire file upwards and/or pause upload and resume it. No need to split it into chunks.
