 * Parse a decimal string into its base unit representation (e.g. ETH -> wei).

 * Accepts scientific notation from either a number or a string. `String(1e-8)`
 * is `"1e-8"`, so any caller that stringifies an amount before passing it here
 * hits that form.
 *
 * @param value The decimal value as a string or number (e.g. "1.5")
 * @param decimals The number of decimal places (e.g. 18 for ETH)
 * @returns The value in base units as a bigint
