EitherFromExpr

given EitherFromExpr[L, R](using `x$1`: Type[L], `x$2`: Type[R], `x$3`: FromExpr[L], `x$4`: FromExpr[R]): FromExpr[Either[L, R]]

Default implementation of FromExpr[Either] - Transform '{Left(x)} into Some(Left(x)) if x can be transformed using FromExpr[L] - Transform '{Right(x)} into Some(Right(x)) if x can be transformed using FromExpr[R] - Otherwise returns None

Default implementation of FromExpr[Either] - Transform '{Left(x)} into Some(Left(x)) if x can be transformed using FromExpr[L] - Transform '{Right(x)} into Some(Right(x)) if x can be transformed using FromExpr[R] - Otherwise returns None
