[FIX] GHDL+Yosys Schematic Viewer Temporary File Spam Fix

[irshbn]

Problem
When schematic viewer calls runYosysGhdl(), it doesn't call remove_file() on the .teroshdl_${random_id} file that it generates with createTempFileInHome(). This results in temporary schematic descriptions needlessly cluttering the user home directory.

Solution
In src/colibri/yosys/yosys.ts add remove_file(outputPathFilename); on line 175:

export function runYosysGhdl(config: e_config, topTevel: string, sources: t_file[],
    callback: (result: e_schematic_result) => void): any {
    // ...
    const exec_i = p.exec(cmd, opt_exec, (result: p_result) => {
        // ...
        remove_file(outputPathFilename); // add this line here
        callback(schematicResult);
    });
    return exec_i;
}

I've tested this on my machine (see additional context) with a couple of vhdl files, and it works as expected.

Alternatives I've considered
If there is a reason you want the file to exist after the schematic viewer call, consider replacing calls to createTempFileInHome() with calls to something like this (appended to src/colibri/process/utils.ts):

/**
 * Get the OS temporary directory path
 * @returns Temporary directory path
**/
export function get_temp_directory(): string {
    const os_temp_dir = os_lib.tempdir();
    return os_temp_dir;
}

/**
 * Create a random file in the dedicated OS temporary directory
 * @returns Path to created random file in temp dir
 **/
export function createTempFileInTmpdir(content: string): string {
    const os_temp_dir = get_temp_directory();
    const random_id = makeid(5);
    const filePath = path_lib.join(os_temp_dir, `.teroshdl_${random_id}`);
    file_utils.save_file_sync(filePath, content);
    return filePath;
}

This way files keep existing in the tempdir, without cluttering home directory.

If the above solution is accepted, remove_file(outputPathFilename) should also be added to other functions as it is missing there as well.
