Any specific reason to have the inception time a day before?

This is how we do it in bns dnssec.sign() as well: https://github.com/chjj/bns/blob/master/lib/dnssec.js#L191
My guess is, its just to ensure that when you deploy there will be very few machines on earth that think the timestamp is invalid. This is especially true for blockchains which have a weird concept of "now".

Closes #29
This PR enables ICANN TLD holders to claim their reserved names on Handshake by signing offline with an HSM. This was an explicit ask by such an interested party that keeps their DNSSEC keys on a hardware signing module that has a PKCS#11 interface. They can not use their production system to sign arbitrary TXT records like Handshake requires, so we need to offer them custom software that still works with their hardware.
Unfortunately this required adding a dependency: https://github.com/PeculiarVentures/pkcs11js
This library could be vendored, but it also contains native code because the PKCS11 interface is literally a C header file. HSM manufacturers provide this library file to their customers who pass it directly into their software clients like OpenDNSSEC and now also,
bns-prove;-)Great docs about the standard: https://www.cryptsoft.com/pkcs11doc/v230/
I used this HSM emulator with PKCS11 support for testing: https://github.com/opendnssec/SoftHSMv2
The test suite in this PR will skip automatically if it is not installed (it expects the pkcs11 interface library to exist at
/usr/local/lib/softhsm/libsofthsm2.so).I added an extra doc
PROVE.mdexplaining all thebns-proveoptions, and linked to it from the main README.I have a few test names reserved in a hard-fork of hsd that I've been using to integrate claims in Bob Wallet. The test for this PR actually reads that ZSK private key from a file and inserts it into the SoftHSM database as a PKCS11 token. After running the test once, I successfully claimed the name on regtest using the command-line utility:
