In ihmeuw-demographics/popMethods: Methods for Population Estimation

Assert that each of the inputs once transformed is a finite value greater than negative Infinity and less than positive Infinity.

1	validate_popReconstruct_inputs(inputs, settings, detailed_settings, value_col)

`inputs`	[`list()`] [`data.table()`] for each ccmpp input. Requires 'srb', 'asfr', 'baseline'; mortality estimates provided as just 'survival' or two of 'mx', 'ax', and 'qx'; and migration estimates provided as just 'net_migration' or both 'immigration' and 'emigration'. See Section: Inputs for more information on each of the required inputs.
`settings`	[`list()`] Named list of settings for running the popReconstruct model with. The required settings are the same as those required for `demCore::ccmpp()`, see Section: Settings for these. The optional settings specific to popReconstruct are described in Section: Optional popReconstruct Settings
`detailed_settings`	[`list()`] Detailed settings for each ccmpp input and 'population'.
`value_col`	[`character(1)`] Name of the column containing the value of interest in each of the `inputs`. Default is 'value'.
