Abstract classes should not have public constructors.
Constructors of abstract classes can only be called in constructors of their subclasses.
So there is no point in making them public.
The protected modifier should be enough.

Removes redundant modifiers from the code.
These modifiers redeclare the default modifiers that apply to interfaces, enums etc.

These array creations are unnecessary because arrays are created automatically for methods using varargs.

`isEmpty()` expresses the intent more clearly and is therefore preferred.
Counting the number of elements can also be an expensive operation e.g. when using linked lists.

While cleaning up the code I found a some more code to cleanup:
* Remove unnecessary boxing
* Use `contains(..)` instead of `indexOf(..) != -1`
* Use `assertInstanceOf` in tests
* Make expensive trace logging conditional
* Remove redundant constructor
* Replace `collect(Collectors.toUnmodifiableList())` with `toList()`
* Replace `filter(..).count() == 0L` with `noneMatch(..)`
* Replace `filter(..).count() > 0` with `anyMatch(..)`

Method references are more readable because they refer to class names and usually result in less code.

Simplifies the code by using List.of, List.copyOf etc. where possible which results in less code and imports.

Stream.toList was introduced in Java 16 and creates an unmodifiable List so it can be used to simplify code whenever the List is not expected to be modified.

* Add more null annotations
* Fix mock name
Adds null annotations to most of the tests as well as a few other classes.
Also fixes a few other SAT findings.
Fixes ~300 SAT findings in total.

When modbus slave responds with explicit error code, we communicate the
user what it means. E.g. error code 2 refers to "Illegal Data Access".
In addition, fixed some simple typos discussed in

Modbus TCP client to read the full modbus message, even if
fragmented/segmented.
Serial/RTU to error more clearly if all bytes are not received as
expected.
