zpay32: remove unused InvoiceFeatures
Originally the feature namespaces were destined to be split, but this
has changed with the introduction of flat features.

zpay32: check invoice length while decoding
This commit checks that the size of the bech32 encoded invoice is not
greater than 7092 bytes, which is the maximum number of bytes that can
fit into a QR code. This mitigates a potential DoS vector where an attacker
could craft a very large bech32 invoice string containing an absurd amount
of route and/or hop hints. If sent to an application that processes
payment requests, this would allocate a burdensome amount of memory
due to the public key parsing for each route/hop hint.

For a 1.7MB payment request, this yielded about 38MB in allocations
from just parsing public keys:

```

         0     0% 96.64%        8MB  1.28%  crypto/elliptic.(*CurveParams).ScalarBaseMult
         0     0% 96.64%       12MB  1.93%  crypto/elliptic.(*CurveParams).ScalarMult
```

With this change, memory usage will be far lower as decoding will exit
early with an error if the invoice is too large.

zpay32: modify an invoice's r field to allow multiple routes
Before this commit, if an invoice encoded multiple `r` fields, we would
decode them as one single route. We fix this by allowing an invoice to
store multiple routes.

6e5477e378 zpay32 test: litecoin decode tests
New tests are added for creating, decoding, and re-encoding
litecoin invoices for both mainnet and testnet, as well as a test
that expects an error when the active network mismatches the
invoice.

zpay32: make expiry time only accessable using Expiry()
This commit renames the invoice field Expiry to expiry, and changes
the type from time.Time to time.Duration. Getting the value of the
field will now have to be done using the getter Expiry(), which
will also return the default invoice expiry (3600s) if it is not set
explicitly by the the invoice.
