Switched key and value in forEach-callback?

[littleant]

I don't know if this is intentional, but the following line seems to be wrong:

slip39-js/src/slip39_helper.js

Line 285 in 4d4675c

shares.forEach((k, v) => {

forEach((k, v) => ...) should be forEach((v, k) => ...).
Below this line the share-value k is compared with the index x.

I currently don't understand the interpolate-function fully, but this doesn't look right to me.
A share is a binary blob, that is compared to an index, which is an integer...
