-------------------
* Added support for setting weight of the pre-drilled depth for B&I2014
* Added support for calculating Liquefaction Potential Index (LPI) and Lateral Displacement Index (LDI)
* Fixed bug where calculation of shear strain from Zhang et al. (2004) used wrong value for interpolating between
different Dr lines, such that upper or lower limit were taken not interpolated value (resulted in slight change of
values for Bray foundation settlement method)
* Added new default cpt loader `load_mpa_cpt_file`, where all values are in MPa and metres and delimeter is ','
* Fixed bug where `big_Q` in B&I2014 triggering method was calculated with the `m` from Eq. 2.15b,
now calculated using the `n` from Robertson and Wride (1997)
