Ensure `derive_channel_keys` doesn't panic if per-run seed is high
b04d1b868fe28bea2e4c711e6e6d2470d2b98d77 changed the way we
calculate the `channel_keys_id` to include the 128-bit
`user_channel_id` as well, shifting the counter up four bytes and
the `starting_time_nanos` field up into the second four bytes.
In `derive_channel_keys` we hash the full `channel_keys_id` with an
HD-derived key from our master seed. Previously, that key was
derived with an index of the per-restart counter, re-calculated by
pulling the second four bytes out of the `user_channel_id`. Because
the `channel_keys_id` fields were shifted up four bytes, that is
now a reference to the `starting_time_nanos` value. This should be
fine, the derivation doesn't really add any value here, its all
being hashed anyway, except that derivation IDs must be below 2^31.
This implies that we panic if the user passes a
`starting_time_nanos` which has the high bit set. For those using
the nanosecond part of the current time this isn't an issue - the
value cannot exceed 1_000_000, which does not have the high bit
set, however, some users may use some other per-run seed.
Thus, here we simply drop the high bit from the seed, ensuring we
don't panic. Note that this is backwards compatible as it only
changes the key derivation in cases where we previously panicked.
Ideally we'd drop the derivation entirely, but that would break
backwards compatibility of key derivation.

Check entire TLV stream instead of by field
This causes a compilation error if a new field is added but missed in
the tests.

Add BOLT 12 merkle root test for `invoice_request`
A BOLT 12 test vector uses an `invoice_request` message that has a
currency, which aren't supported, so using OfferBuilder::build_unchecked
is required to avoid a panic.

Builder for creating invoice requests
Add a builder for creating invoice requests for an offer given a
payer_id. Other settings may be optional depending on the offer and
duplicative settings will override previous settings. Building produces
a semantically valid `invoice_request` message for the offer, which then
can be signed for the payer_id.
