Gorm Chained Clauses() does not apply grouping parentheses correctly

Description

If you chain two clauses together, the library doesn't properly parenthesize the combined expression. e.g.

DB.Clauses(&clause.Expr{
    SQL: `id = 1 OR id = 2`,
}, &clause.Expr{
    SQL: `name = "bar"`,
}).Find(&results)

generates the following SQL query: SELECT * FROM `companies` WHERE id = 1 OR id = 2 AND name = "bar"

but it should be SELECT * FROM `companies` WHERE (id = 1 OR id = 2) AND name = "bar"

clause.Expr is designed to be used in raw sql. use clause.Or
