fix indicator name

I checked the output values of your RMA implementation and they correlate with the values listed here:

• https://runkit.com/anandaravindan/wema
• https://tulipindicators.org/wilders

From your implementation (i.e. this.smooth = 1 / this.period) you seem to have implemented Wilder's Smoothing which is not a Relative Moving Average (RMA).

wow, that's true
please add unit test for WEMA, for example. And rename other RMA to WEMA here

import { WEMA as WEMA1 } from 'technicalindicators';
import { WEMA as WEMA2 } from '../../src/wema';

describe.only('Relative Moving Average', () => {
    const ticks = [120, 150, 240, 540, 210, 380, 120, 870, 250, 1100, 500, 950];

    it('Cross validate', () => {
        const cross = new WEMA1({ period: 6, values: [] });
        const local = new WEMA2(6);

        ticks.forEach((tick, idx) => {
            const calcValue = cross.nextValue(tick);
            const crossValue = local.nextValue(tick);

            if (idx > 6) {
                expect(calcValue).toEqual(crossValue);
            }
        });
    });
});
