* reworked some of the das core specs, pr'd to check whether whether the conflicting type issue is centric to my machine or not
* bumped nim-blscurve to 9c6e80c6109133c0af3025654f5a8820282cff05, same as unstable
* bumped nim-eth2-scenarios, nim-nat-traversal at par with unstable, added more pathches, made peerdas devnet branch backward compatible, peerdas passing new ssz tests as per alpha3, disabled electra fixture tests, as branch hasn't been rebased for a while
* refactor test fixture files
* rm: serializeDataColumn
* refactor: took data columns extracted from blobs during block proposal to the heap
* disable blob broadcast in pd devnet
* fix addBlock in message router
* fix: data column iterator
* added debug checkpoints to check CI
* refactor if else conditions
* add: updated das core specs to alpha 3, and unit tests pass
#6087 introduced a subtle change to `nim-web3` resulting in `Gwei` to be
serialized differently than before. Using a `distinct` type for `Gwei`
improves type safety and avoids such problems in the future.
In Nim 2.0, the `test_fixture_operations` files fail to compile with:
```
Error: 'result' is of type <Result[system.void, system.cstring]> which cannot be captured as it would violate memory safety, declared here: /nimbus-eth2/tests/consensus_spec/bellatrix/test_fixture_operations.nim(130, 5); using '-d:nimNoLentIterators' helps in some cases. Consider using a <ref Result[system.void, system.cstring]> which can be captured.
```
Wrapping the `applyExecutionPayload` in a factory that takes `path`
avoids this problem.
Suite names were not being used because `test` has to have access to it
during instantiation - this PR cleans things up a little while at the
same time upgrading unittest2.
* require sync committee supermajority in CI
To better catch problems with sync committee messages in CI, extend
local testnet simulation to also verify that each block is signed
by a supermajority of the sync committee.
Requires #5083 and #5084
* lint
