This fixes a build error with Rust 1.53.0 and lexical-core 0.7.4
From the Rust 1.53.0 release notes:
The added BITS constant may conflict with external definitions. In particular,
this was known to be a problem in the lexical-core crate, but they have
published fixes for semantic versions 0.4 through 0.7. To update this dependency
alone, use cargo update -p lexical-core.
