version bump to 0.8.1

[mario4tier]

Bumps the wrapper version to 0.8.1 on dev. This PR changes the code only; merging to master, tagging and releasing are not part of it.

What changed

Two lines, following the same shape as the last release bumps (8cadf5b for 0.8.0, a9ff1b4 for 0.7.1):

file	change
pyproject.toml	version = "0.8.0" -> "0.8.1"
talib/__init__.py	__version__ = '0.8.0' -> '0.8.1'

Nothing else needed to change:

• CHANGELOG: already has its 0.8.1 heading on dev, with the entries for the stream handles, InsufficientHistory, the SUPERTREND output names and the empty-input fix.
• Other version strings: a search of the tree for 0.8.0 outside CHANGELOG found only these two lines. talib/_ta_lib.c does not contain the wrapper version. The _ta_lib.c change inside a9ff1b4 was a Cython build-metadata block, unrelated to the version.
• TA-Lib C: the required version stays 0.8.1 (tests/test_func.py, wheels.yml TALIB_C_VER).

Checks

On dev at 6712c9e (this PR's parent), in a fresh clone against TA-Lib C 0.8.1 built from the v0.8.1 tag:

• Full suite: 1697 passed.
• Regeneration: tools/generate_func.py, generate_stream.py (and --stub) and generate_abstract_stub.py reproduce _func.pxi, _stream.pxi, stream.pyi and abstract.pyi byte for byte. cython talib/_ta_lib.pyx (Cython 3.3.0, numpy 2.2.0) reproduces _ta_lib.c byte for byte with no warnings.
• CI: Tests (dev) green on Python 3.9 to 3.14.

On this branch:

• sdist: ta_lib-0.8.1.tar.gz has Version: 0.8.1 and contains _ta_lib.c, _ta_lib.pyx, both .pxi files, the three stubs and py.typed.
• Wheel built from the sdist: the isolated build (Cython 3.3.0, numpy 2.5.3 from PyPI) installed into a fresh venv. talib.__version__ is 0.8.1, and the suite passes outside the source tree (1697 passed).
• Install without Cython: installing from the sdist compiles the committed _ta_lib.c, and the suite passes outside the tree (1697 passed).

For both installs, tests/test_stubs.py reads the stubs from ../talib, so the installed .pyi files were copied next to the tests for that run.
