read_model

<code>read_model</code> converts SEM arrow notation to <code>model</code> describing SEM parameters

Applies dynamic structural equation models to time-series data
with generic and simplified specification for simultaneous and lagged
effects. Methods are described in Thorson et al. (2024)
"Dynamic structural equation models synthesize ecosystem dynamics
constrained by ecological mechanisms."
