Build a self-start model formula with optional fixed parameters

Constructs x ~ fn(t, ...) with each free parameter as a bare symbol and each fixed parameter substituted as its constant value.

build_ss_formula(fn, params, fix = list(), x, t)

`fn`	Symbol; the self-start model function.
`params`	Character vector of parameter names in `fn` argument order.
`fix`	Named list of fixed parameter values.
`x`, `t`	Character; the response and time column names (see `fit_names()`), so the returned model predicts on the original channel names.
