Re-use the existing market rate data, and only fetch new data. This should
reduce the number of retries needed as we can reliably get a hundred or so
data points before disconnection.

Pick up where we left off, and fetch the remainder of the market rate data on
disconnection. WebSocket disconnections seem frequent, but random, with the
Boerse API.

If-Modified-Since must be provided a date that was previously returned as a
response's Last-Modified header, else it doesn't have any effect.
Store each response's Last-Modified header in a magic comment in the resulting
file; then re-read it avoid re-fetching the same data multiple times.

The new token- and Websocket-based API needs two more headers.
These also require a SHA256 hash, so replace the md5 package with ironclad,
which is already pulled in by another package anyway.

Periodic transactions can be used to forecast future income and expenses
without entering it manually for all future months.
This only applies after the very last posted transaction, so future-dated
transactions block periodic transactions completely until their posting date.

This lets me see at least the valid data in the plots while editing my ledger
file. Most of the time, errors will come from the end-of-month "balances"
posting, which only asserts accounts' observed balances.

When running `ledgerplot -e` on a weekend, it would keep re-fetching the same
