Add ASME matching tensile analysis

[reverendbedford]

Adds a method for tensile data analysis that exactly matches the ASME spreadsheet.

[Copilot]

Pull Request Overview

Adds a new ASME-matching tensile analysis workflow and supporting correlation classes.

• Split the original ASME polynomial correlation into “Simple” and “Standard” variants with clear analyze implementations.
• Introduce TensileDataAnalysis and ASMETensileDataAnalysis for dataset-driven yield and tensile regression.
• Add asme_tensile_analysis helper in methods.py for constrained polynomial fitting.

• The constructor for StandardASMEPolynomialTimeIndependentCorrelation lists F, S0, and T0 but the docstring only describes poly. Please document all parameters (F, S0, T0, and poly) with their purpose and units.

    def __init__(self, F, S0, T0, poly, *args, **kwargs):

pycreep/time_independent.py:421

• The docstring states the default analysis_temp_units is "K", but the code initializes it to "degC" unless overridden by the caller. Please align the documentation with the actual default or update the default setting in code.

                                    default is "K"

pycreep/time_independent.py:279

• The SimpleASMEPolynomialTimeIndependentCorrelation class references self.F, self.S0, self.T0, and self.coefs in its analyze method without defining them in an __init__. Consider adding an initializer to set these attributes or inheriting parameters properly.
