fix: Fixed some flaky tests dues to floating point errors

[coolsidd]

Fixed shouldGenerateNearbyGPSCoordinateWithOriginInKilometers and shouldGenerateNearbyGPSCoordinateWithOriginInMiles

Ran all tests locally using the following python script:

import subprocess
from tqdm import tqdm

def run_command(command):
    process = subprocess.Popen(command, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
    output, error = process.communicate()
    if process.returncode != 0:
        print(f"Command failed with exit code {process.returncode}:")
        print(error.decode())
        return False
    return output.decode()

def run_command_with_progress_bar(command, iterations):
    for i in tqdm(range(iterations), desc="Running command", unit="iteration"):
        output = run_command(command)
        if output is None:
            break

if __name__ == "__main__":
    command = "ctest"
    iterations = 100
    run_command_with_progress_bar(command, iterations)

The test shouldGenerateSlovakiaStreetAddress is also flaky returning out of bounds errors sometimes.
