Issue
#376requires dynamic-length blob, fixed-length bit map, fixed-length bit array, optional, and fixed-length boolean support. The reviewed head containsDynamicBlobDeclarationandBooleanDeclaration, andTypeAliasParseralready dispatches their field classes. This PR adds and dispatchesBitArrayDeclaration,BitMapDeclaration, andOptionalDeclaration. The PR adds parser, declaration, definition, and focused test coverage for the three added classes.

Explanation
The changes stay within issue
#376. The alias-resolution change limits replacement to field-class properties and supports references used by field-class parsing. Its tests cover aliases in the new optional and related field-class locations. The remaining changes add implementation, parser support, constants, exports, and tests for the requested field classes.

- Around line 136-137: Update the range conversion using rangeArray in
OptionalDeclarationParser to catch overflow and non-numeric conversion failures
from getAsBigInteger().longValueExact(), and report them as ParseException so
they do not escape as unchecked exceptions. Keep the existing signed long range
representation; do not add support for unsigned bounds above Long.MAX_VALUE.

Parse the optional field class, whose field is enabled by a boolean or integer selector field, and decode its fields. This commit was made with the help of Claude Opus 5.5 Signed-off-by: Arnaud Fiorini <fiorini.arnaud@gmail.com>
A field class alias name was replaced by its field class in any string property of the metadata, so a structure member named like an alias had its name replaced. Only resolve the properties listed by the specification, and test the alias resolution of each of them.

What it does
Fixes #376. Implements the missing ctf2 field classes in separate commits. As bit map are defined as bit arrays in the CTF2 standard, bit map inherits from bit array's class.
It also adds a test and fixes a potential issue for aliases where it should be replaced only in a subset of fields.
How to test
Tests have been added to validate functionality, I do not have any trace that currently uses those field classes. LTTng 2.17 will generate bit maps and optionals so when a release candidate is available, we could generate some traces to test those features.
