* [leopard] add github.com/status-im/nim-leopard to vendor
* [leopard] specify absolute path for nimcache dir
* [leopard] make adjustments to nim-dagger CI GHA workflow
* use storestream for retrieval
* use `len` prop on manifest
* remove read pattern
* make blocksize and chunksize consistent
* fix tests
* fix chunker tests - now padded by default
Introduce new nimble 'test' task that runs *all* tests.
Renames testAll to testDagger, because testAll didn't
run all tests, it forgot to run the contract tests.
* initial commit of the Shacham RSA-based public scheme
Minimal working version with lots of error checks and corrections
still needed.
- using Bearssl RSA code through libp2p
- with selecteble BigInt library for experimentation

* using normal file io instead of memfiles
mmap has serveral potential issues and we do not really need it, so
changing to use the normal system file interface is better.

* fix getSector
* fixing DST tag in hashToG1
The DST tag should be unique to achieve domain separation
of hash functions as defined in:
https://tools.ietf.org/id/draft-irtf-cfrg-hash-to-curve-06.html#domain-separation
Changed DST tag to one that indicates the PoC status of this code.

* add optimized verifyPairing implementation
When verifying two pairings, one final exponentiation
can be spared through the use of cneg.

* speed up tag generation by a factor of s
Scalar multiplications in tag generation can be rearranged
to benefit from the way random points are being generated.
Since random points are themselves generated using scalar
multiplication and the base is common, the sum of multiplications
becomes a single multiplication with the scalar sum, resulting in
a nice speedup.

* use blst_p1_add_or_double instead of blst_p1_add
blst exposes two add functions: one that works for the corner case
of doubling, and one that isn't. It seems safer to use the one that
works, even if it is highly improbable in these cases that doubling
would occur.
