/**
 * Builds a regular expression object from a simple string pattern.
 *
 * A string pattern can use the following special characters:
 *  - `*` to match any number of characters: `"foo*"` will match all strings starting with `"foo"`
 *  - `?` to match a single character: `"foo?"` will match all strings of 4 characters that start with `"foo"`
 *  - `\` to escape a special character: `\*` will be interpreted as `*`, and `\\` will be interpreted as `\`
 *
 * This is a replacement function for `ct/_string.stringPatternToRegExp`.
 *
 * @example
 * ```ts
 * import { createRegexFromPattern } from "apprt-core/string-pattern";
 * const regex = createRegexFromPattern("foo*");
 * const match = regex.test("foobar"); // true
 * ```
 *
 * @param pattern a simple string pattern conforming to the rules above
 * @param ignoreCase whether the regular expression should be case insensitive (false by default)
 * @returns A regular expression implementing the pattern
