Binary size too big!

[ncw]

We use github.com/henrybear327/go-proton-api in the Proton drive backend for rclone.

I've just discovered in rclone/rclone#7998 that the protondrive backend is adding over 3.5MiB to the rclone binary! That is nearly 5% of the binary size. Most backends weigh in at about 200k - it is only the ones with big external SDKs that exceed 1MB and the protondrive is the second biggest after storj.

I suspect that this package is pulling in more things than it needs to which are making its way into the rclone binary.

I used https://github.com/Zxilly/go-size-analyzer to examine the rclone binary and it wasn't obvious where the extra code size was coming from.

Any ideas?
