This is now set by sbt-ci-release

sbt-ci-release changes the commands required to publish to Sonatype.
While this may be a desirable change at some point, it is inconsistent
with other repos. Reverting for the time being.

* Add SortModules to transform to def-before-use

Adds a new transform, SortModules, that transforms a FIRRTL circuit
to enforce an invariant of modules and external modules being defined
before use. This transform is left as optional in the event that a
user may wish to have a quick way of getting the circuit to respect
this property as may be expected of some other tool, e.g., MLIR.

Verilator 4.034 was complaining about wires being named weak and strong
because those are SV 2009 keywords.  Added them to the Utils.v_keywords list

* Make MultiTargetAnnotation.targets a def

This enables the annotation writer to choose their own underlying data structure

* Update MultiTargetAnnotation ScalaDoc

Uses sbt-ci-release for automation

It would replace them with a validif node with a UIntLiteral which can
lead to type errors.

this fixes issues #1934

Fix verilog prep

* Make Stage.run protected

Change the access modifier of Stage.run from no modifier to protected.
This method is really an internal API that the user implements with
the main entry point for a Stage being "execute" or "transform". By
allowing users to access "run" they can bypass checks, mandatory file
reads/writes, and wrappers.

Fix "fix" for negative literals > 32 bits

Overflow of 32-bit Int would cause any negative literal value equal to
-(2^(width % 32 - 1)) where width >= 32 to be incorrectly inverted

VerilogMemDelays: fix lowering of direct mem-to-mem connections

* Also clean up VerilogMemDelaySpec structure

Also speed up common case of Array[Byte]

now points to apache 2.0

Both use EliminateTargetPaths to duplicate modules based on annotations.
Currently, EliminateTargetPaths API is a little too limited so it
duplicates more than it should which effectively breaks Dedup whenever
DontTouchAnnotations are present.

Also, make ConstProp and DCE treat all HasDontTouches as local
annotations even if they are instance annotations. This is more
conservative but it is generally better to preserve deduplication than
to maximally optimize every instance.
