fmt_beta: Round and format regression model coefficients
Description
Takes in a vector of regression model coefficients, and returns a
rounded and formatted coefficient vector. This is the default
rounding for models formatted with fmt_regression(). Coefficients
larger than 100 are rounded to the nearest integer, between 10 and 100 to one
decimal place, and all others to 2 decimal places. These thresholds were
selected with odds ratios and hazard ratios in mind.
