Equal-Tailed Hybrid Confidence Interval

1 2	ci_hybrid_unbiased(estimates, st_errs, conf_level = 0.95, beta = (1 - conf_level)/10)

`estimates`	numeric vector A vector of estimates. Will return a confidence interval for the maximum estimate.
`st_errs`	numeric vector A vector of estimated standard errors for each estimate.
`conf_level`	double in (0,1) The desired confidence level of the resulting interval. Note that conditional and hybrid confidence intervals don't have nominal coverage in the conventional sense.
`beta`	double in [0, 1 - conf_level] For hybrid intervals, degree of mixing between conditional and unconditional intervals. At 0, hybrid intervals are identical to conditional intervals.
